Flywheel SINGLE MASS LIGHTWEIGHT BMW M50 M52 M54 M57 - 5,85 kg.

Single Mass Lightweight Flywheel BMW M50 M52 M54 M57 (5850G)
This lightweight flywheel replaces the heavy dual mass unit and delivers faster throttle response, stronger reliability and the option to run the extremely durable BMW manual gearboxes. Perfect for motorsport or converting an automatic daily driver to manual.

Besides fitting M20, M50, M52, M54 and M57 engines, it is also fully compatible with BMW M43 and M44 engines, as they share the same crankshaft bolt pattern. Correct clutch selection is essential: you must use a 240 mm clutch kit that matches your gearbox input shaft and ensure that the starter gear engagement matches the ring gear. Using mixed dual-mass components will cause problems on M43/M44.

Prepared for 240 mm single-disc clutch from BMW E38/E39/E46 M57D30.
