I have the Spec Stage II and it's by far the best clutch I've ever had. And as Ponygrl420 stated, I beat the piss outta the car and the clutch has never given me issues. Hell, the throwout bearing was my only problem and I called SPEC 6 monthsafter the clutch was installed and they still overnighted me a new improved throwout bearing after the fact. Can't complain about that type of customer service either!
