The Exedy FF01 Lightweight Flywheel is engineered for high-performance driving, combining a reduced weight of approximately 12.7 pounds with superior thermal capacity for consistent engine response. Manufactured from a single piece of billet chromoly steel, this flywheel delivers exceptional durability and heat management under both racing and street conditions.
Its low-inertia design allows for quicker engine acceleration and sharper throttle response, making it well-suited for lightly tuned racing cars, autocross, drag racing, rally events, and spirited daily driving. The integrated ring gear teeth eliminate the risk of separation common in pressed-on designs, ensuring long-term reliability at high RPMs. Independently tested and SFI approved, the FF01 is certified to withstand engine speeds up to 18,000 RPM, providing confidence in demanding environments.
With precise engineering and proven performance, the Exedy FF01 is a trusted upgrade for Subaru Impreza, Baja, Forester, and Saab 9-2X Aero H4 models, offering enthusiasts a balance of responsiveness, durability, and safety.
