The centerforce clutches for the FWD GM cars is about the same as stock anyways. They usually can't fit the weight setup inside the bell housing. I have had a
Clutchmasters FX300 in my beretta on it's 2nd engine, 2nd flywheel and 3rd transmission now and it still holds up to the 3400 great. That's probably what i will put in the Alero when it needs one, as well as a lightweight Fidanza flywheel (which i also have on the 3400).
I've also heard good things about SPEC clutches.
