That stock clutch will cook real quick with a few stabs in 4th if your running +/- 300rwkw.. I give it probly 3 or 4 hits and it'll be slipping... might even let go on your 1st 4th gear pull depending on how the boost comes on. It'll piss you off hard having that kind of power and the clutch just lets go all the time, ruins the fun.LOL! Def. save for a clutch too, but dont buy something that'll just do the job for now IMO, especially if you think theres a chance you could end up around the 400 mark someday. Just means instead of paying 5-600bux dif. now you will just throw away your clutch that you spent 1700bux on and then buy another clutch for 2300bux give or take.. that's alot of wasted cash IMO. The gearboxs are pretty tuff dude, just make sure your fully in gear before getting into it and dont rush your changes all the time, the thing should last.
