The SPEC aluminum flywheel for 2010–2012 BMW 335i/135i replaces the heavier OEM unit with a lighter, balanced aluminum assembly to sharpen engine response and reduce rotational mass. Intended for street and performance use, the flywheel works with compatible clutch systems to provide crisper throttle response and quicker rev changes while maintaining durability appropriate for upgraded drivetrain applications when paired with correctly matched clutch components.
