i'd look into ACT extreme cluitches. they grab really nice and can handle alot of power. Might wanna read up on which dick to get with it.

just so ya know, usually aftermarket clutches tend to make the clutch a little stiffer. you get used to it, and you'll be barking 2.nd and 3rd in no time.
they also grab as soon as you let off the clutch a little bit..at least mine does. it's an awesome feeling. :-)
clutchmasters is another reputable company.
