Exedy MF02 Lightweight Racing Flywheel Chromoly Steel

The Exedy MF02 Racing Flywheel is a lightweight, high-performance flywheel designed for Mitsubishi Mirage vehicles equipped with the 4G92 engine. Engineered to combine low weight, low inertia, and high thermal capacity, this flywheel delivers ultimate performance while retaining supreme driveability for street use, drag racing, autocross, rally, and track applications.

Key Features:

• Constructed from solid one-piece billet chromoly steel forging for superior strength and durability
• Weighs only 11.9 lbs (5.38 kg), significantly reducing rotational mass for improved engine response
• Gas nitrided surface treatment provides superior hardness and wear characteristics
• Integrated ring gear teeth prevent separation issues common with aluminum flywheels
• Enhanced airflow design improves clutch cooling during high-performance operation
• Tested to 18,000 RPM and certified to SFI specification 1.1 for competitive motorsports use
• Compatible with Exedy Stage 1 Organic, Stage 2 Sports, and Stage 2 Racing clutches
• Direct replacement for OEM flywheel with full compatibility

Unlike conventional aluminum or multi-piece flywheels, the Exedy MF02 features an integral ring gear design that eliminates the risk of separation due to different expansion coefficients. The chromoly steel construction offers an excellent strength-to-weight ratio while the gas nitriding process ensures compatibility with ceramic puck-style clutch discs and all friction materials. This flywheel provides better response and output in high-speed operation without sacrificing low-speed torque, making it ideal for both street driving and competitive motorsports.
