My Indy just replaced the clutch and flywheel in my 2009 C2S. He used a Sachs clutch as the replacement. I have google searched, reviewed Rennlist, 6Speed and BMW online forums and I cannot get a consistent answer on how to break in the clutch properly. Some sites say to drive 100 - 200 miles without hard acceleration, some sites say 500 - 1000 miles, my Indy says between 100 and 200 miles with the throttle no more than 25% to 50% engaged. Anyone out there have any real world experience?

 

Me? Drive it like you normally would.

 

Drive normally. Mine stopped stinking after about 300-400 miles which I thought was weird.

 

I never heard of breaking in a clutch.

 

What Big smoke says.

I drive my Boxster, use its clutch, the same way today with over 300K miles on the original clutch as the day I bought the car. Done that for every other manual transmission equipped car I've owned.

Same with the Turbo. Well, I didn't buy the Turbo new, but I use the clutch the same way I use the Boxster's clutch. The Turbo has almost 145K miles on its factory clutch and I expect it to last a long time. (At 120K miles had the tranny out for a RMS leak and the clutch disc had no measureable wear.)

Be sure you adhere to the 2 year brake/clutch fluid flush/bleed schedule. "Old" brake/clutch fluid while it does not appear to affect braking system function/performance -- but even so that is not an excuse to ignore the flush/bleed schedule -- did have a negative effect on my Boxster's clutch action and shifting action.
