Clutch Masters FW-CM4-SF Lightweight Steel Flywheel - 240mm Conversion

The Clutch Masters FW-CM4-SF is a precision-engineered lightweight steel flywheel designed specifically for BMW E85/E86 Z4M applications. This 240mm conversion flywheel offers improved throttle response and quicker rev characteristics compared to the factory dual-mass flywheel, making it an ideal upgrade for performance-oriented driving.

Key Features:

• CNC machined from high-grade 1045 or 4140 steel billet for maximum strength and durability
• Black oxide coating provides rust prevention and a distinctive black finish
• Zero balanced for smooth operation and vibration-free performance
• SFI certified for use in sanctioned racing and motorsport applications
• Laser engraved with Clutch Masters logo and part number for authenticity
• Proudly designed and manufactured in the USA

Important Compatibility Note: This is a 240mm conversion flywheel that will NOT work with OEM clutch kits. It is engineered exclusively for use with Clutch Masters FX100, FX200, FX300, FX400, and FX500 series conversion clutch kits. The lightweight design reduces rotational mass, allowing your engine to rev more freely and providing improved acceleration and throttle response.

Every Clutch Masters flywheel undergoes rigorous quality control throughout the manufacturing process, with craftsmen continuously checking critical measurements to ensure exact tolerances are met. This attention to detail ensures reliable performance for both street and track applications.
