RFY Light flywheel

Racing Factory Yamamoto has engineered the ideal flywheel solution for the NSX enthusiast, addressing the specific needs of both early and late model cars. This flywheel replaces the heavy factory unit to deliver a significant improvement in engine acceleration, throttle feel, and driver connection, yet not too light still adequately balancing the odd fire 90 degree setup.

Application for NA1 (1990-1996 / 5-Speed)

For owners of the original 5-speed NSX, this is a direct, bolt-in replacement for the factory 7.1kg single-mass flywheel. The significant weight reduction is the key to unlocking the famously sharp and immediate engine response of the coveted NA1 Type-R, completely transforming the feel of your C30A engine.

Application for NA2 (1997-2005 / 6-Speed)

For owners of the later 6-speed models, this flywheel serves as a critical performance conversion component. It allows you to replace the extremely heavy, response-dampening OEM dual-mass flywheel with a lightweight single-mass system. This conversion offers a dramatic, night-and-day improvement in engine responsiveness.

• Conversion Note: To install this flywheel on a 6-speed car, you must use a clutch kit designed for the 5-speed (NA1) models using a NSX-R input shaft

Engineering & Performance Data:

• Material: High-Strength Chromoly Steel
• RFY Weight: 5.2 kg
• OEM 5-Speed Single-Mass Weight: 7.1 kg
• Rotational Mass Reduction (vs. 5-Speed OEM): A 1.9 kg (26%) reduction. The weight savings and response gains are even more significant when converting a 6-speed car from its factory dual-mass flywheel.
• Heat Management: The robust single-mass chromoly design offers superior thermal stability and heat dissipation, crucial for spirited driving.

Compatibility:

• 5-Speed Models: Direct replacement, compatible with the standard OEM clutch assembly.
• 6-Speed Models: Conversion part, requires the use of an NA1 / 5-speed style clutch kit.
