Flywheel (Aluminum), Clutch Masters - F22 M240i, F3X 340i/440i, B58

Upgrading to a lightweight aluminum flywheel on your B58 M240i, 340i, 440i has many advantages:

+ eliminate potential failures from the original Dual-Mass Flywheel
+ faster revs from less rotational mass
+ more power to the wheels

Upgrading to an aluminum flywheel not only has performance benefits but is also a smart move to prevent a potentially catastrophic flywheel failure. Aluminum flywheels are a single-mass design - machined from 6061-T6 aluminum with a replaceable steel clutch plate. This makes the flywheel lighter and simpler, two things that are appreciated for better performance and reliability. Because aluminum is the lightest flywheel available we recommend this for mostly track-focused cars. Steel is also available for performance street use.

New mounting bolts and pilot bearing included.
