I can deal with the chatter... I've been drag racing for a long time... I've driven hi horsepower clutch driven cars and it seems to me that they are just heavier really.. .Have to get used to them... My biggest question is "Do they hold up" with horsepower numbers I am making... You know? I just don't want to take the tranny out, change the clutch, then have it perform as bad as the centerforce did... I went through two of them.. I don't want to make that mistake a third time... Whats up Adrenalin!! Yep, broke my car again...
