JB Racing Aluminum Lightweight Flywheels

These lightweight aluminum flywheels significantly lower the high rotating mass of your stock flywheel, allowing your engine to rev quicker. Makes shifting faster and rev-matching much easier.

JB Racing's lightweight aluminum OEM replacement flywheels are designed to provide performance enhancements for street driven vehicles. by reducing static weight and Moment of Inertia (MOI), the lightweight aluminum flywheel allows the engine to rev more quickly. It takes less horsepower to accelerate the lightweight flywheel, thus allowing more horsepower to reach the wheels.

Lightweight aluminum flywheels are manufactured from billet aluminum and are viewed as "single-mass" designs. These flywheels duplicate the critical dimensions of the OEM flywheels for the application listed, and are designed to accept the OE clutch components (EXCEPTION - new design E36 M3 flywheels accept sprung-hub M5 clutch discs - see our clutch/flywheel packages or call/email for more information). JBR flywheels are manufactured are state-of-the-art CNC equipment. All flywheels are designed, CNC machined, assembled, balanced, inspected, and packaged at JB Racing.
