Lightweight Chromoly Flywheel

The Cusco Lightweight Flywheel is designed to improve engine response by reducing rotational mass compared to the factory flywheel. Weighing approximately 4.8 kg (10.6 lbs), it is around 48% lighter than the OEM flywheel, allowing the engine to rev up and drop RPM more quickly.

Constructed from SCM435H chromium-molybdenum steel, this flywheel combines reduced weight with strength and durability for street, spirited driving, and track applications. The reduced rotational inertia helps deliver a more responsive driving experience, making it a worthwhile upgrade for drivers looking to get more out of the FA20 or FA24 platform.
