I'm running a cc stage 4 and I have no complaints as far as clamping force and pedal pressure. I do however feel that the clutch was the reason I hurt my first motor, I killed my thrust washers to the point they fell out and I had really crazy crank walk, my oil pump failed and my Vtc gear all because of metal shavings! Ill continue with this clutch but will be swapping to a tilton cmc and be putting a pedal stop in to keep from putting more pressure on the pressure plate then is needed.
