Fidanza Performance Aluminum Flywheel 130231 for Select 1998-2007 Toyota, Chevrolet, and Pontiac

Fits select 1998-2007 Toyota Corolla, Matrix, Celica GT, MR2 Spyder, Chevrolet Prizm, and Pontiac Vibe.

The Fidanza Performance Aluminum Flywheel (MPN 130231) is engineered to significantly reduce rotational mass compared to heavy factory cast-iron units. Weighing 40% to 60% less than stock, this flywheel reduces the engine's moment of inertia (MOI), resulting in faster throttle response, quicker acceleration, and more efficient power delivery to the ground. This is a direct bolt-on component designed for high-performance street and track use.

• Precision Engineering: CNC machined from high-grade billet 6061 T6 or 2024 T4 aluminum for an optimal strength-to-weight ratio.
• Replaceable Friction Surface: Features a bolt-on, heat-treated 1050 steel friction plate. This modular design allows you to replace only the wear surface rather than the entire flywheel when performing clutch service.
• Durable Ring Gear: Includes a hardened 1050 steel ring gear secured with military-spec fasteners for long-term reliability and high-RPM stability.
• Improved Driveability: Stepped dowels (on most applications) ensure precise alignment and balance for smooth engine operation.
