ignore rangcrx... he either knows a lot about nothing or just has some serious problems getting information out.

Anyhoo, I've personally had a centerforce, and I can tell you they're crap. Mine fell apart within 4 months, threw 2 springs from the disk. I've also had an Exedy, very well built clutch. OEM ITR clutches are great too, good feel, inexpensive, and if your OEM pressure plate is in good shape, you should have no problem with just purchasing an OEM disk. If you're pushing some power, I'd suggest getting ahold of Miguel at Bay City Clutch with your specs and having him custom build you a clutch. He's very knowledgable, and can work pretty good deals with straight clutch systems, or hybrids.

Everyone is going to have something to say about one brand or another, personally if it were me, i'd steer clear of ACT or Centerforce, and stick with OEM, Exedy, or Clutchmasters, or even a hybrid of those three brands.
