Made for the S50/52 in combination with a standard S50/52 clutch set. The flywheel is made of very strong Chromoly and weighs only 5.5kg (standard M50 double mass is 11.2kg).
There are of course clutch kits available with a stronger plate and/or heavier pressure group, they can also be applied to this flywheel. This can be interesting if driving with a lot of power. For example, sets from Clutch Masters.
Due to the low weight, it will greatly improve the response of the engine and acceleration also increases. Less power is needed to rev the flywheel and this power then reaches the wheels immediately. (less drive-train-loss)
Fits:
-E36 M3 + Z3M
M3 3.0 and 3.2
And on all M50-M54 (or M20 with m50 starter motor) and 5-speed BMW manual transmissions if you use the S50 clutch with it, as partnr's (21211223076, 21211223347, 21211226220, 21211226221)
General information on flywheels:
It is a widespread belief that a larger/heavier flywheel is used to give the engine more torque, and that the torque will decrease with a lighter flywheel. This is NOT the case. Heavy flywheels are used purely for easy clutch engagement so that grandma can drive off without stalling, nothing more and nothing less. Once the car rolls, a heavy flywheel becomes completely unnecessary. The driveline and the weight of the car already have so much momentum that a heavy flywheel does not add much. Extra weight, especially on the crankshaft, then makes the car less fast in terms of acceleration. So if you don't intend to drive like a granny then a light flywheel gives only advantage.
The experience is that the engine response is much better and the car accelerates a lot faster!
