4140 Japanese Forged Chromoly Flywheel

The FX Racing Lightweight Chromoly Flywheel is engineered for superior performance and longevity, utilizing 4140 Japanese forged chromoly steel, offering twice the strength of standard billet steel. Its design incorporates enhanced airflow channels to significantly improve clutch cooling, crucial for high-performance applications. This flywheel is meticulously CAD designed, CNC machined, and computer balanced to ensure precise operation and a significant reduction in rotational mass, contributing to quicker engine response. It meets or exceeds the SFI 1.1 specification, meeting stringent safety standards for racing and performance use. The flywheel weighs a mere 18 lbs, offering a substantial weight saving over stock components. A critical note for installation is that replacing a stock OE dual mass flywheel with this unit may introduce additional gear noise. After professional installation, a break-in period of 500 miles is required. This product replaces the stock OE dual mass flywheel and is compatible with multiple BMW models including the 325, 328, 525, 528, M3, and Z3 (E36, E39), as well as specific Infiniti G35 and Nissan 350Z models.
