Intuitively, I think the vast majority of clutch kits sold for these cars come right off the shelf! Would you agree?
Just because a new aftermarket part is sold does not mean it is in correct balance. We have seen brand new aftermarket flywheels (non Porsche) that were more than 20 grams out of balance.
