I'm running around 332whp on Buschur's dyno and the factory clutch is doing just fine. However I don't launch my car. I do however drive/shift aggressively on occasion.

 

I'm on the stock clutch, too. Power in sig. I rev high, hate to be off the throttle, run WOT as often as possible, but no launching.

 

what you need to realize is, read your waranty it will say also that they have the right to replace any faulty product with a used one thats how waranty companys work. and if there has been alot of mods done to the car the waranty company will not cover it. this happend to me with my car. it also says that in the fine detail to.
