Steve,
I had to have my clutch replaced at 9000 miles in my M5. It had never been abused. There is no doubt that MOST people believe the OEM clutch/pressure plate to be the Achilles Heel of the M5, (along with crap brakes on the track).
When you have the clutch replaced, the service dept. will tell you to be extremely easy on the clutch for the first 300-500 miles. This is because the clutch is very slightly conical in shape, and takes a short time to conform properly to the pressure plate; i.e. so that both surfaces fit flush. If this initial 'clutch break-in' process is not followed, your brand new clutch can be essentially ruined from the start, leading to increased problems as it ages.
