I have just taken the clutch off my flywheel and found it to be an ap racing one with the clutch friction plate itself looking almost new. in the middle where the input shaft goes is a bit wobbly compared to the new black doamond clutch i have bought. I will need to skim the flywheel and the black diamond clutch is larger. Do you recommend keeping the ap one using it as the plate looks soo good, or just fit the black one?Also why is it larger than the ap one?
