for sale resurficed and rebalanced single mass flywheel.
it is oem m50b20 s/m flywheel at oem speck, there for no need to change starter or anything at all. just get oem m50b20 clutch with springs in it and pressure plate.
flyheel is 228mm but i tested itmy self and it holds 328i coupe without slippin clutch, and i tryd my best to make the clucth slip.

what you get is,
no messing about with fitting, as its 1:1
starter stays the same
improved acceleration as flywheel is lighter
no juggering as with m20 flywheels couse its still havy enough to avoid that
resurce to machine it down to any weight you want even to go up to 240mm surfice for m3 purposes or upgraded 328i's
flywheel is very road user friendly, as you get performance, without loosing to much comfort
price, 100e +15e carier anywhere in ireland and NI

11kg is quite heavy!!! Standard is 12-15 if I remember right and I've never really noticed significant juddering with 5.9kg M20 flywheels. Only really start noticing it when you go down to 3-4kg and to be honest, most issues depend on what clutch is being used.


Still, 100 is very cheap for a bolt on smf upgraded :)

Cant mind what weight it was, have to double check. Weight diference between std double mass is big enough to be noticable on acceleration.
I'm working on adjusting this flywheel to suit m3 pressure plate. So soon it will be available on 240mm setup
