[MA128]

I've seen a few references to this on other threads but nothing definitive. The car has 58,000 miles and I occasionally get a shudder or chatter at low revs taking off from a stop. Seems a little worse after the engine/transmission warm up. It also is getting worse as the miles accumulate.

I had thought, naturally enough, that the problem was with the clutch or flywheel. This will seem crazy but the problem has been solved - by installing the M3 rear subframe bushings! I had my suspension upgraded this week (see my signature) and the shudder has disappeared. I've tried repeatedly to make it shudder and it won't. Pure conjecture - the bushings were so soft that the differential and drive shaft had some fore/aft motion that interfered with smooth engagement.
