I'm currently in the market for a new clutch. So after reading a lot of threads on Stangnet I hear you guys love the Centerforce Dual Friction clutches. They sound really nice and hear nothing but good things from them. I am tryin to steer away from SPEC clutches, I'm currently using their stage 1 clutch and billet flywheel and its got about 1k miles on it now and has yet to stop chattering. Can't complain about it holding power, it does have that covered well it's just not for me. My car is procharged and makes 423rwhp but I really only go to the strip maybe once or twice a year. So I'm looking for a clutch with good holding power and not a super stiff clutch. My buddy has one is his chevrolet 4x4 and says they are pretty stiff, BUT they don't chatter which is high on my list now. Any input on the Centerforce DF clutches or even their I and II clutches which I see on their website would be a HUGE help to me. Thanks guys and have a good weekend.
