haha no the shielding gas Im getting local. I have to get a 220 volt outlet put in my garage. all the other stuff has to be ordered. I decided to take the a-arms off and cut all the dead wieght but now I got more work to attach them to the frame and get the measurements right. but its worth losing about 60 pounds. Ill need some adjustable coilovers to. You can see where I ran a thick bolt thrugh the swingarm bolt to attach angle iron to be a mounting point. and I made simple brackets for the computer behind the gas tank. Ill relocatthe battery to somehere low and up front. http://a610.ac-images.myspacecdn.com/images01/112/l_ccd3dd76efd462faccd5807b85914979.jpg

one of the best things about these reverse trikes is that they register and insure as a motorcycle. So you can demolish practicaly every car and out handle them and get good gas mileage and only pay $150 a year for insurance. good deal
WickedRaven

I agree, but the concept is the same. Also similar in layout to the Aptera. Where did you get the from suspension from? what vehicle?
I have a set of tri-magnum plans somewhere. interesting concept but I wanted rack and pinion and IFS.
I need to find coil overs that are the more adjustable screw type and can adjust the gas as well

Air bags are lighter than springs and you can go low tech and just use a schrader valve and a piece of tubing. The tank can be any piece of the frame that will hold air. A lot of service vehicles use the bumbers because they're easy to access/add on.
Complexity comes from the solenoids and other toys. The only thing you really need is a valve and a gauge for each bag. Much easier than choosing the right spring and getting it adjusted.

Did you ride the short bus? it's a trike, it doesn't lean. it uses a HUGE contact patch and sticky rubber to hold the road like a CAR, not a lean angle.

J DOLLAZ! ------------ the front axel is going to be the biggest pain in the ass out of the whole project. I have to get all the measurement and mounting points perfect and symetrical. Im going to start on the frame by building a square upside down u-shaped piece that will connect to where the forks used to be. and the u shaped piece will rest on the ground and be level. from there I will design the floorpan frame so that I the upper and lower a arms can be easily moved around and attached. Those flat metal pieces you see will be trimmed to get the measurements right and tack it all into place before welding the a arms to the frame. after the a-arms are all welded into place Ill buy some coilovers like these that speedway motors has. http://www.speedwaymotors.com/eccStoreFront/product_images/2005/721395_L.jpg

its realy not heavy at all. how it is right now I can pick the front up and move it around like a rick-shaw chinese cart. the front wheels tires and a-arms for each side about 50 pounds. It will be under 1000 pounds when completely done framing and putting skin on the beast. Performance mods are in the back of my mind right now. from other reverse trikes Ive seen with weight/horsepower ratio this will be one sick machine that will be able to fly and still hold some serious lateral g's. Ill prob get a gear reduction kit for more low end torque after its finished but that is not my main concern. I put the exhaust bracket on today and took the foot pegs off. YES the exhaust is removable. . . there are two bolts below where I welded it http://a315.ac-images.myspacecdn.com/images01/74/l_b323c9446c0b24a686ee3b2f15e80f2a.jpg

Custom body or what? whats in store for the exterior??
MoltnAuto
08-30-2008, 09:53 AM
for the body I will make it out of a combo of hard pink insulation foam and stretching cloth across parts. the pink foam is easily sandable and readily available and cheap at hardware stores. all I have to do is cover it with aluminum foil so the resin doesnt eat it. I would use the cloth stretching method the same way it is used in making custom sub box enclusures. simply stretch cloth over complicated feutures and brush on resin...then reinforce with fiberglass mat and cloth. I have mold/mother mold making experience and would most likely use the body of this one as the plug for a mother mold to use on other vehicles. for the paint I would like to incorporate some heat reactive paint like this

Im just curious how much would be a fair price people would pay for one of these. Here are the specs on what it will most likely be able to do. Dont forget that it registers as a motorcycle so insurance is still dirt cheap. I just bought a lexan windshield. I was going to use a glass windshield but I will do that on the next one. I will also make this so it somehow has a complete canvas enclosure that can be easily attached so you can drive in the rain without getting wet and store it behind the seats. There is also something called plexus to put on the lexan windshield so rain beads off just like rain-x. It will also have skin/fairings and air intakes and exhausts so the engine is covered but well ventilated.

I think you are doing a great job so far-:-D
BUT.
My personal opinion is that its going to end up looking a little too 'homebuilt' to be viable as competition to the other trikes- unless its silly cheap.
It was 100% great until you put the front tubes on- the flat lexan front windscreen is an instant turn off for me.
I'd way prefer things if it was closer to how the Arial Atom is styled. Would be way more awesome if you cut those front tubes off and instead used 2x motorcycle windshields..... But thats just my opinion, remember :-)

09-09-2008, 07:00 AM
yea I know what you mean. I agree and I am not 100% thriilled on the frame design but I am being EXTRA safety conscience on this one. here is one that I have no information on but it is a homebuilt reverse trike that is done great and is how I would like to do my next one. the drawback with the open top design is driving it in the rain. I need some sort of a roof that stores in the unit. not being able to drive it in even the slightest rain is a big turnoff for a lot of consumers. and with having long supports running between the passanger seats its going to be extra hard for your lady friend to be bending her head over to your side to bob for apples :makeout but I still want to make an open top one next
what about setting it up to have a removable roof, or a set of t-tops?

I was able to use a level and see how the steering geometry was set up on a trex so Ill use some of those ideas and ones that Ive read. all the random scraps you see welded on the a-arms actualy hold it in place so that I can move the entire wheel around wile maintaining the geometry. this way I can make mounts easier. its going have an 80 inch wide track!!!! I moved the wheelbase close to the center of gravity as well. the wheels were originaly centered around your foot but now they are centered around your thighs. this thing is going to be really spacious inside and the seats are fully adjustable.

when the wheels are straight it has a little negative camber (the bottom of the wheel is further out than the top) . Its set up with a few degrees posative caster. when its the outside wheel durring a turn it has negative camber. when its the inside wheel durring a turn it has postive camber. for each mounting point there is supposed to be two brackets. (one on each side) but I just put one bracket on each for now to verify geometry http://a192.ac-images.myspacecdn.com/images01/72/l_5d57c43b6250643a125378fd3952c477.jpg

09-22-2008, 01:38 PM
very cool dude. I have begun buying parts to do basically the same thing... copy the T-rex. Right now im working with a 2007 R1 motor, swing arm, and frame. I just got the tire taken off one of my track spare wheels. Im putting it on a lathe and cutting the right lip off. Then im putting a 4-4.5in section of aluminum into the cut space to create a 10-10.5in rear wheel to run a 315/35/17 rear tire... the same process they use to widen car wheels. With this i will cut the swing arm down the center and make it wider also. This way i can retain the cush drive and use the stock sprockets. I will have to make a new axle as well as a mount to make the brake inboard the wheel off the swing arm (design is a bit more complex). I also have an extra rear caliper hanger laying around. I plan to cut it down and fit it so its an underslung brake... so essentially the rear wheel has two brakes... one for braking and one will be a hydrolic parking brake...
As for the front suspension I just got two spindles off a 4wd S-10/blazer (2 piston vs. the 2wd is a 1 piston). With those i will run s-10 calipers, and rotors. I will make my own upper and lower control arms from aluminum (lighter weight) and probably use the Pinto/Mustang II style manual rack and pinion (very popular on kit cars). I will be using a rocker arm style coilover setup on the front to get the most amount of adjustabiliy as possible.
For the rear suspension i will be using the stock shock, but probably double it up and run two of them on a rocker style inboard setup (depending on final weight and distribution).
Basically one of my main goals is to go as light as possible. I have all the experience needed and i have the supplies/can order them. I have like 200 yards total of light and heavy carbon fiber so it will be used a lot. I will be making my own seats, body, and floorboards out of carbon and fiberglass and some sandwich foam/honeycomb style construction. So basically the frame will be 1.5 1/16 wall steel (same as t-rex), the body and floor pan will be CF/fiberglass, the seat will be CF buckets with sewn pads (like the aluminum racing ones), and the suspension will be for the most part all aluminum. I would love to hit the 700-800lbs mark, but im thinking realisticly it will be 800-900lbs
For the future and more power, im probably going to look into a light forced induction setup like a small turbo and intercooler... hence the 315 rear steam roller tire.
Ive thought this out a ton, as you have, but it looks like im taking a similar yet different route. Best of luck to you! Ill keep this thread marked and start my own when my project officially starts. Maybe we can meet up at the Tail of the Dragon when were both done!

I was really looking into gettin a nice wide tire on the back but when it all added up I decided to just use a car tire on the stock rim. the guy said it was the hardest tire hes ever put on anything so it shouldnt be going anywhere. I pretty much dove into the whole project with moderate research. You got a mandrel tube bender as well I am guessing? are you having a roof or convertible like the electric trex?
the blue devil
09-22-2008, 10:51 PM
Right now thats my biggest decision... i dont know if i want a VW GX3 style or t-rex. As for the tire, yea it will be more work but the traction will be worth it. A car tire mounts the same way as a bike tire so yours will be fine. The bead will hold it tight from spinning... worst case throw some bead locks on haha (not recommending this) but i doubt you will get the traction to spin the tire on the rim and not the ground.
I have no doubt it will be hard as hell for the tire guys. I dont have any tire connections here like i used to or i would just go in and use the machine to mount it on my own. Having worked at a cycle shop nothing is worse then a harley guy coming in with a 300 series to be mounted to a nice chrome rim. Its goin to suck but its their job haha. Just lube it up haha.
If i go gx3 style i would make a removable soft top like a jeep wrangler and a bolt on windshield. This way its all weather worthy.
As for tools i have a 220 Miller MIG, torches, air tools, hand tools, and im lookin into that same bender you have... want to rent it to me when your done :dunno seriously though? I only plan to make one so i don't want to drop $700. I plan to tack everything up and then take it to work and use the 220v TIG welder to finish all the welds. This way they look good and they're strong as hell.
This will be my Midwest winter fun project. I probably wont start it for another month or so. Just collecting parts and getting the small stuff done like the rear wheel and swing arm.

well the dual wheel gave me a great idea... i have an extra R6 wheel... so the R6 wheel with the R1 wheel would be 11.5in. Perfect for a 315 rear. Just have to shave down the inner two lips enough to allow for the tire to deflect enough that it wont hurt the wheel or tire. Probably cut both lips off and add in a section on the middle. Also solves the issue of the rear brake caliper. Plus it looks pretty cool having two sets of spokes!
Now i just need to keep getting all my parts. The way i learned it is the chassis is just a giant bracket that connects everything. You have to have everything to design it around, not the other way around.
Focusing on the front uprights and brakes right now. Looking at doing a Mustang II uprights with a 11in rotor... a complete rebuilt front with spindles, hubs, rotors, and calipers can be bought for $350ish shipped.

Thats the plan for me right now. Just bought the spindles and 11in brake kit for the mustang II. Now im going to order the manual steering rack so i can get all my dimensions to work out the front suspension setup for caster/camber/bumpsteer/ect.
As for the motor and bike frame, I plan to remove the motor from the bike frame, weld up a jig inside the bike frame that will have the mounting points of the motor, and use that to build the rough frame around. Yesterday i cleaned off the gargage floor and all and layed down tape to get ideas of sizes needed for seating space, motor and drive train space, and to get an idea on wheel base and front width. I havent jumped into this too hard yet as i just moved into my new house and im waiting on finances to settle a bit as well as the shitty weather to roll in.
Also i have decided to go with an open cockpit style like the VW GX3 and have a removable soft top... i have renderings of the body style but ill put those up when the project comes to a close. Cant give away all the details and info yet :thumbup

I picked up the extension cables for it today but dont have time to wire it today. http://c3.ac-images.myspacecdn.com/images02/27/l_7941da9d839e41a8b6e9136168c108fa.jpg http://c2.ac-images.myspacecdn.com/images02/17/l_74a447cad8b845adb70ff5733bcf3a0d.jpg http://c3.ac-images.myspacecdn.com/images02/7/l_d137ea11af314bf4896c8e16a800c60e.jpg http://c3.ac-images.myspacecdn.com/images02/34/l_9ac732a8898841ff95ac4b166ba58b3a.jpg

be carefull when doing this. You need a layer to seperate the foam from the resin or the resin will eat right through the foam. I have been workin for the past few weeks making my own plug for a Ricaro style carbon fiber seat. I used Acrylic paint as a seperator, but the resin leaked through a few areas and destroyed the foam. Its been a pain the the a$$ to fix, but im getting there. The plug should be all wetsanded and ready for a glass mold to be layed over it this week. Ill lay the glass up on the plug, then pull the gass and brace it when cured. From there i just lay in the Carbon cloth, put support foam/balsa in different areas, pull the carbon, trim, and i have my own custom thin light weight carbon fiber race seat. Then ill repeat this for the second. I have the carbon cloth laying around so i figured i would put it to use. It will cut a ton of weight from the car and it will be cheaper then a pair of seats for me. Just takes time (about 20+ hours into it already), but the end results are worth it.
Once the seats are done ill be ordering my spindles, rotors, hubs, and calipers. From there ill get the exact measurements i want to run uneven a-arms that will acheive -.5* camber at rest, around -3* camber at 4in compression, and 1*at 1.5in droop. I know im going to go a bit overkill on my suspension, but in the end the handling will be worth it. Ill also probably make the a-arms from aerotube instead of the traditional round tube. I like your thinking on the front springs for the suspension. I actually bought two 2006 rear springs about two weeks back for $30/ea. Cant beat that because you can swap out the coils for different spring rates if desired. Because ill be running inboard suspension ill be able to control my spring rate with different ratio rocker arms instead of new springs. Another bonus to this is you can easily change the ride height without changing the proload of the springs (for road / track use).
Body and frame design wise i have decided to steer clear of the T-rex style as there are so many replicas like it. Ill be doing my own design that most closely reflects that of the VW concept GX3. With this it will still be a full tube frame Chassis, but i will make my own subframe structure for the motor so i can pull it out/ put it in easily and ill scrap the frame.
Should be pretty cool in the end. Hopefully ill be buying the steel for the frame in the next month time permitting. Between School (16 credits) and work (40 hrs) im pretty limited on my time. Its good to see this thread as its like an inspiration for me lol. Your work looks great man. Keep it up!
Ill post some pics of my progress on the seat later as i have been taking pictures to document the work required.
The seat will be pretty close to this.:

use epoxy instead of poly resin, it wont eat through the foam at all. I have done carbon fibre projects with pink "home depot" insulation foam many times with good success. i usually sand the final shape of the foam, with 220, then paint with a few coats of latex. you can fill any imperfections in your foam with light weight wall spackle, and sand before painting. wet sanding your dry latex will improve the final finish. put a few coats of wax on your mold before you start with the epoxy. in case you dont already know acetone will melt that foam very quickly, great for intricate areas, but messy. the layer of latex paint is verrry helpful here, as it peels away from your finished piece cleanly and the "skin" will contain the acetone/foam mess. Please keep in mind, the very expensive carbon fibre seats you see from the likes of sparco, momo, recaro, etc. are made using pre-preg carbon fibre assuring the proper mix of resin and cloth, and cured in an auto-clave. both resulting in superior strength over a diy wet lay up in your garage. in an impact if carbon fibre reaches its breaking point it breaks in wicked sharp shards, which could be deadly.

Yea i know about the polyester vs. the Epoxy. Im using epoxy on the final part but i have a gallon of polyester sitting in my garage that i wanted to use up before it went bad. Also i know about the autoclave and the prepreg stuff. Wish i had the cash and resources for that one. Mine will just have to be a bit thicker. Although im not planning to do a just wet layup on it. I fully plan to vaccuum bag the seat to get the best resin consistancy and to suck out all the unneeded resin. As for the carbon breaking part, yea i know that too lol... learned that hard way when i wanted to strength test a part and ended up cutting myself pretty good.
As for my plug i made it out of the home depot foam, and painted it up with latex. Because i wanted the glass like finish on the top surface and not the bottom i opted to go the Seat from the mold - mold from the plug route. I like knowing i can make multiple parts and that they will have a useable nice surface right from the mold. After all the sanding to make the plug smooth, its the last thing i want to do on the final parts.
Right now the plug is almost finised. I just have to cut out a few thin areas and fill them. Other then that ive sanded it up to 220. I just need to go through and sand it all the way through the wetsanding stages for a gloss like finish... then wax up, spray the PVA on, and lay several layers of chopped mat. Then pull the glass off the plug, trim, and i have a near perfect mold. Cant wait to start laying in the carbon and see a finished part.
Ill be starting the chassis next month. Just talked to my buddy and my 2007 R1 donor motor and swing arm is strapped down to its pallet and just needs to get shipped (looking for shipping options on this now).

ah yes the power of geometry... actually in theory if the spring is at any angle different then the suspension travel then the spring rate changes as the suspension moves. Example being at rest the coil/shock is closer to verticle then when the suspension is at maximum compression. So in theory the spring rate is higher at rest then it is at full compression, but by very little... pretty easy to figure out with any basic statics/dynamics knowledge. Finally those engineering classes are paying off for me :lol

Interested to see the steering completed and the amount of play or slop in it. Just a thought, but you might want to check into some different rack and pinion setups that might be more suitable. They have ones where the pinion gear comes out the middle. If you ran one like this you could run the steering rod right down between the passeneger and drivers leg area. This would make it so you would only need one u-joint instead of 3 doubles (6 u-joints total). Also are you using a colapsable steering rod for crash safety reasons (you know so the steering wheel doesnt come out of the dash into you in the event of a front end crash).
Also with the suspension what degree of camber are you seeing at full compression and full droop? Are your steering drag link ends in line with the upper and lower a-arm mounts and mainly the reaction points to eliminate any and all bump steer? With your suspension setup the way it is, where are your reaction points and where is your roll center at a static stance with driver weight included?
Guess the last thing is what type of Caster angle are you going to run? Have you considered tilting the upper a-arm back to create an anti dive situation for braking?
Not trying to be Captain Safety here, but i have read it several times and still no one has called it out. I guess my biggest thing is, if you plan on selling this, or trying to build and sell these, you might want to cut back on all the public advertising that you were "drunk" or "hammered" and working on this. It is just irresponsible. When it comes to welding as most know, the surface may look great, but a welds strength is in its penetration. My personal experience with working in the automotive industry is your reputation would be destroyed for this type of work. Working on a vehicle that has the potential to harm or take the life of you or more importantly a PASSENGER while under the influence is just irresponsible. Would you jump on your bike drunk and ride... and have a passenger jump on too? Just keep it smart and keep it safe.

yea i see hes doing okay, but you cant test the caster, camber, and how the car will react to bumps, turns, ect while in a garage... but you can design to get the response your looking for. Im sure you can agree its alot easier to design with room for adjustment rather then take a shot in the dark and *hope* to be able to adjust it to what you need.
I guess ive been fortunate to work with SAE Formula teams and i have had a ton of brains to pick at to learn.
I guess what im trying to say, is dont be afraid to ask people. If you want to throw some ideas, measurements, or questions up... I would have no problem helping in design a bit. Suspension design is so complex its insane. With something like this it wont be perfect, but you can get pretty damn close.

the blue devil
11-12-2008, 08:29 AM
....its best guess at the best!!
Sorry, but I disagree. There is way more room to measure and preplan then using a tape measure for alignment. Alignment isnt a big deal at all, its simply setting the Toe in/out which can be done with any car at anytime, and your right it usually isnt done till the end.
My arguement is more on first and foremost the Camber, followed by the caster and bumpsteer. You dont need a weighted car infront of you, all you need is a calculator, paper, and a pencil.
I guess ill start with the topic of buying a preloaded suspension. Its a great idea as it makes a process a lot easier and eliminates a lot of time spent on planning with rod ends and ball joints, however a production suspension is far less capable of being adjusted. The problem isnt in the parts themselves, but in the angles, heights, and methods in which they are attached.
First off, camber... probably the largest component in determining how a car is going to handle on a straight, entering a turn, the apex of the turn, and exiting a turn. At each point, each tire (working with fronts here, not rear) will see a different camber based on the suspension and its amount of compression. Because the suspension already has a set value for the upper A-arm length, lower A-arm length, and the spindle length it makes the numbers a bit easier. In a simple non complex way, all you really get to change is the distance between the mounting points of the lower and upper A-arms, the angle at which they are mounted, and the camber of the vehicle at loaded at rest. With this simple number you can calculate what the camber will be at 1", 2", 3", 4" of compression as well as 1" and 2" of suspension droop.
Heres an example, lets start with these values that will not change:
Upper A-arm Length: 7in
Lower A-arm Length: 10in
Spindle Height: 8in
Caster angle at reast: -0.5*
Distance between A-arm Mounts: ??
So heres some numbers:
Distance between a-arm mounts with above values: 7.6in
Angle of lower A-arm at rest: -2*
Camber at rest: -0.5*
Results... which actually turned out pretty good!
Camber at 1in compression: -0.9*
Camber at 2in compression: -1.4*
Camber at 3in compression: -2.3*
Camber at 4in compression: -3.4*
Camber at 0.5in droop: 0*
Camber at 1.5in droop: +0.3*
Camber at 2.5in droop: +0.6*
Heres a example of how wrong it can go!
Distance between a-arm mounts with above values: 5in
Angle of lower A-arm at rest: +10*
Camber at rest: -0.5*
Results... this would be a death trap!!!
Camber at 1in compression: -2.3*
Camber at 2in compression: -5.0*
Camber at 3in compression: -8.4*
Camber at 4in compression: -11.6*
Camber at 0.5in droop: +1.1*
Camber at 1.5in droop: +3.6*
Camber at 2.5in droop: +6.5*
With a simple change in mounting point distances (change of 2.6in) and lower a-arm angles (change of 12*)... the results can be catastrophic to the handling!
***Whether the car is weighted or not has no effect on these numbers. The ride height can easily be changed with the shock mounting point
Second, Caster... The is pretty simple, but it has a huge effect on how the car tracks. A lot of tracking depends on the toe in/out, but most of it depends on the angle of the spindle (looking at it from the side of the car). For tracking and steering reasons you want the spindle angled towards the back of the car. To achieve this, you need to offset the mounts from each other. Heres a picture to explain...
http://www.rqriley.com/images/fig-7.gif
Third... the angle and spring rate of the shocks used. You can achieve the numbers you want with a few small calculations, instead of guessing, its quite simple. A small amount of knowledge of geometry (angles, lengths, sin, cos, tan of triangles) will get you everything. Heres an example, you buy a R1 rear spring/shock combo. Lets pretend it has a 500 lb/in spring rate (which is correct i beleive). If you want a spring rate of 500lb/in for the car you will need to mount this perfectly perpendicular, because at any other angle the rate will be less then 500lb/in. So lets say you want the car to have a 250lb/in spring rate.... well then mount the shock at 45* (500sin45*=250)... if you want a spring rate of 350lb/in then setup a right angle triangle. The verticle value is the value you want to achieve. The hypotenuse will be the 500lb/in spring rate. From this the horizontal value can be calculated but is useless. Simply solve for the angles of the triangle and you can find how to mount it! While the initial value is this easy, it gets more complex but these are really not needed unless you are using progressive springs or hardcore racing.... as the spring compresses, the angle at which the spring is mounted actually changes. So basically as the suspension compresses and rebounds the spring rate will change, but very minimally.
So lets put this all together and learn how to apply it. Solve for all your variables and the values you want. Your going to want to map this all out so you have measurements of the car at rest and loaded. When making the chassis you use these measurements and mounting points to mount the a-arms, spindles, and steering rack. To get the ride height of the car to match the ride height and angles of the car on paper, you simply adjust the mounting point of the shock (not the angle, but the height)... (another great part of inboard springs... ride height adjustment)...
Simple as that lol... you dont need a person in the car, or the weight of the driver or passenger to come up with these numbers. You just need to take your time and solve for them. If you spend 15 hours to find them, it will greatly benefit the hundreds of hours of fabrication as well as hundreds of hours of driving. Why spend time making it look good if it handles like crap?
If you have a hard time measuring and building a frame to these specs the smart thing would be to build a jig for all the mounting points... then build a frame into the jig....

PS if you dont know what values you want like caster and camber... read the internet for the optimum amounts...
If you want to build a car the first thing you should do is go buy Carrol Smiths book on building and designing a race car... it will be the best investment you ever made.

Sorry, but I disagree. There is way more room to measure and preplan then using a tape measure for alignment. Alignment isnt a big deal at all, its simply setting the Toe in/out which can be done with any car at anytime, and your right it usually isnt done till the end.
My arguement is more on first and foremost the Camber, followed by the caster and bumpsteer. You dont need a weighted car infront of you, all you need is a calculator, paper, and a pencil.
I guess ill start with the topic of buying a preloaded suspension. Its a great idea as it makes a process a lot easier and eliminates a lot of time spent on planning with rod ends and ball joints, however a production suspension is far less capable of being adjusted. The problem isnt in the parts themselves, but in the angles, heights, and methods in which they are attached.
First off, camber... probably the largest component in determining how a car is going to handle on a straight, entering a turn, the apex of the turn, and exiting a turn. At each point, each tire (working with fronts here, not rear) will see a different camber based on the suspension and its amount of compression. Because the suspension already has a set value for the upper A-arm length, lower A-arm length, and the spindle length it makes the numbers a bit easier. In a simple non complex way, all you really get to change is the distance between the mounting points of the lower and upper A-arms, the angle at which they are mounted, and the camber of the vehicle at loaded at rest. With this simple number you can calculate what the camber will be at 1", 2", 3", 4" of compression as well as 1" and 2" of suspension droop.
Heres an example, lets start with these values that will not change:
Upper A-arm Length: 7in
Lower A-arm Length: 10in
Spindle Height: 8in
Caster angle at reast: -0.5*
Distance between A-arm Mounts: ??
So heres some numbers:
Distance between a-arm mounts with above values: 7.6in
Angle of lower A-arm at rest: -2*
Camber at rest: -0.5*
Results... which actually turned out pretty good!
Camber at 1in compression: -0.9*
Camber at 2in compression: -1.4*
Camber at 3in compression: -2.3*
Camber at 4in compression: -3.4*
Camber at 0.5in droop: 0*
Camber at 1.5in droop: +0.3*
Camber at 2.5in droop: +0.6*
Heres a example of how wrong it can go!
Distance between a-arm mounts with above values: 5in
Angle of lower A-arm at rest: +10*
Camber at rest: -0.5*
Results... this would be a death trap!!!
Camber at 1in compression: -2.3*
Camber at 2in compression: -5.0*
Camber at 3in compression: -8.4*
Camber at 4in compression: -11.6*
Camber at 0.5in droop: +1.1*
Camber at 1.5in droop: +3.6*
Camber at 2.5in droop: +6.5*

just got the taillights. they are DOT approved. which is hard to find inexpensive decent looking dot approved lights. they will be recessed/ a.k.a. "flush mounted" to the body. REAL flush mount where it doesnt stick out past the body. they are brake/running/turn signalling so these will be the only lights on the rear of the vehicle. Ill be wiring them soon boys and girls. I ordered dual filament DOT approved sealed headlights through a local shop FTF Cycles in Randolph MA that should arrive tuesday. I will have to make my own adjustable housing for the lamps but it will be saving me about $80 to make my own housing. Does anyone know where I can get a DOT APPROVED very thin strip of AMBER "Yellow" turn signals that are about 3 to 7 inches long? I repeat DOT APPROVED HAS TO BE RIGHT ON THE TURN SIGNALS. http://c2.ac-images.myspacecdn.com/images02/57/l_43b5c38980144e44bde2639d5b8a2035.jpg

I guess my presence and willing to share knowledge on something being built is not appreciated. No offense taken. Just keep your "if it can drive down the road" idea alive. Safety should be an utmost concern for a machine that is capable of reaching 120mph and higher with a passenger. I guess I just lack the ability to connect how important DOT lights are, yet how insignificant suspension design and safety are. This isn't some gocart that will go down the road 5mph... This is a car capable of taking your life in an instant.

heres a couple pics to show YESS I am still working on it but not as often as I would like to these days. The more I read about steering geometry I believe I will have to completely re-do the geometry for the passenger wheel I already put on so I ordered a book on custom building kit-car geometry suspension. http://c4.ac-images.myspacecdn.com/images02/50/l_a75ac8fc2ab94450b4bb18a5ae57c4cb.jpg it wasnt to hard to make the first side...but copying the dimensions to be the ecact same from the center of the vehicle is where its hard. http://c3.ac-images.myspacecdn.com/images02/30/l_d041e83913c443aa90fe934784a18b42.jpg i put a bolt thru the lower control arm and attached a level and right angle. There will be the same setup on both wheels to align them together. I will remove the clear plastic angle finder and put a square tube to connect them and perfectly align both wheels. then I'll tac-weld the lower control arm into place. then I will be able to remove my homemade alignment tool and weld in control arm mounting brackets

I was thinking about how I would do a project like this .... carpenters level for 6 and 12 oclock position (on level ground) would work ok for camber....and a tape measure at 3 and 9 oclock position for the toe settings......caster is a different story....positive caster means the lower ball joint is slightly forward of upper ball joint .... I Don't have specs for how much..... but I remember years ago maybe about a degree and a half for that OEM front end.....problem being you got to have some kind of alighnment machine to measure this......and this alignment spec is important to good tracking......on all alignment racks you can't drive a three wheel vehicle onto the rack....you would have to make a center track of somesorts to support the rear wheel.....while checking the alighnment........if you brought it to my shop I would make this happen with maybe wooden support bridge in the middle...but thats just me thinking of a possible ways....like my past posts suggest.....its not a OEM front end so its all up in the air on what the best specs might be for the application......different front end retroffitted on to something different would most certainly mean different specs ....you would have to play around with the alignment to get it right....hope this helps ...PM if you want specs for the year and make of the front end being retrofited....may be a good starting point...

Sorry to hear about the stearing issues,
I believe someone spotted that a while ago and tried to help.
Still wanting to see the outcome!
This thread may be dead, but I just thought of a question......how are you going to back that thing up? Are you putting reverse on it somehow?
Word, LOL... do it Flintstone style..:drunk::drunk:
