I can vouch that Sam has a brand new, genuine BMW clutch and OEM flywheel assembly in his car, with all new exhaust mounts front and rear and new crank pilot bearing, less than a week old.
The car also has new M5 thrust arm bushes and fully refurbished calipers front and rear with drilled floating discs.
The flywheel I posted a few weeks ago WAS NOT from this car, but shown from another I was doing at the time.
Good luck with the sale.
