How many is to many? I have a set of Sc-1s on my ZX-10. I have 4 trackdays on them and they still look great. I used warmers for all 4 days and all the runs were at VIR. There is no bluing at all..... Hell the tires look like they have 1 session on them. I guess I need to pick it up a notch or 3... but in the mean time for all you tire guys do you think they would be alright for a double at Jennings in Feb. These are the Pirelli Dragon Slicks.
