Just making sure, Clutch Slip

Was at streets of willow a few weeks back and near the end of the day I would upshift (I have a quickshift) and the clutch would completely give... had 2 let off the throttle until it caught again. Ordered graves clutch plates, will this fix the problem or could there be other causes. Im pretty confident that this is the issue but I am just making sure. (I am also running full synthetic) Never changed the friction plates before (20k+ miles). Is there any special tools or parts that i'll need (besides new cover gasket)

I'd change the plates too. better to do it all at once.

Did it a while ago. Didnt change the plates just because they cost money I didn't have. Already had a trackday on them @ infinion. Only problem I had was when using my QS from 1st to 2nd it was dropping back into N.

Adjust the kill time for a shorter time.
