The gearbox was a warentee job so free, the labor was free for the clucth as a result but BMW would not replace it unless found defective. Well it was not defective as they saw it but at 50,000 miles it was worn and the car from day one chudderd badly at times engaging the clutch when hot and here it is hot much of the time...I hate it, I am trying to figure a way to meet a nice UK lady and move there as potty as that might sound LOL!!! The dealer would do teh work but only with genuine BMW parts so a light weight flywheel was out really unless I could have figured out some other combination of parts and got away from the dual mass, but I could not come up with a parts list that would for sure work. The 240MM M3 setup is much more robust than the 208MM stock setup and it is actually a few pounds lighter as well. The chudder went away and when it hooks up it hooks up and I had thought maybe one day putting a supercharger/turbo on it so instead of leaving in a worn stock setup I had it all upgraded to M3 as the cost was within pennies and as it turned out my flywheel was not defective but was not working properly either as no resistance for about 10 degrees of rotation.
Best bet is a light one but I feels some are too light really, I want one about 14-16 pounds as that I think would be ideal as too light with our low torque I don't think is a plus.
