My sprung Stage 2 on an Aasco flywheel has only a minor amount of chatter, easily hidden by the exhaust. Unfortunately, the AP Racing clutch on my M3 chatters like nobody's business.
Pulling gearboxes and engines on these cars isn't quite as easy as it is on a 996 (which is worlds more work than pulling an air cooler), but I'll yank a Porsche gearbox or engine out LONG before I will on a BMW.
