Upgrade your Honda S2000 with the Fidanza 191581 aluminum flywheel, designed to reduce rotating mass and improve engine response. This high-performance flywheel is approximately 40–60% lighter than the original equipment unit, helping the engine accelerate more quickly and respond faster to throttle inputs. Its lower moment of inertia supports quicker rev matching and sharper performance for street, track, and enthusiast applications.

The Fidanza 191581 features a billet aluminum body manufactured from 6061-T6 or 2024-T4 aluminum, providing a strong and lightweight foundation. A heat-treated friction plate delivers dependable clutch engagement, excellent grip, and extended service life. The friction plate is bolted on and replaceable, allowing the flywheel to be serviced without replacing the complete assembly.

Reliability is reinforced with military-spec fasteners and a replaceable hardened 1050 steel ring gear. Stepped dowels are included on most applications to promote accurate installation and secure alignment. This flywheel is engineered for select Honda S2000 applications using 2.0L and 2.2L engines and is intended for performance-focused builds where reduced rotating weight and improved throttle response are priorities. Professional installation is recommended, and proper clutch, fastener, and application compatibility should be confirmed before installation. This product may expose you to chemicals known to the State of California to cause cancer or reproductive harm.
