JB Racing Aluminum Lightweight Flywheel – E36 M3

The JB Racing Aluminum Lightweight Flywheel significantly decreases the high rotating mass of the stock E36 M3 flywheel, enabling your engine to rev more quickly. This results in faster shifting and effortless rev-matching.

JB Racing’s lightweight aluminum replacement flywheels are engineered to enhance performance in street-driven vehicles. By reducing static weight and Moment of Inertia (MOI), the lightweight aluminum flywheel allows the engine to rev faster and requires less power to accelerate, thereby delivering more power to the wheels.

These lightweight aluminum flywheels are crafted from billet aluminum and feature a “single-mass” design. The newly designed E36 M3 flywheels are compatible with sprung-hub M5 clutch discs—check out our clutch/flywheel packages or contact us for more details. JB Racing flywheels are produced using state-of-the-art CNC equipment and are meticulously designed, machined, assembled, balanced, inspected, and packaged at JB Racing.

JB Racing is one of the most respected machine shops in the country, trusted by numerous professional race teams for precision machining of engines and driveline components. Their BMW flywheels are built with the same precision and quality relied upon by these winning teams, setting them apart from typical market offerings. Standard features include:

– CNC-machined flywheel, zero-balanced to eliminate vibration
– Replaceable hardened steel clutch surface, bolted (not riveted)
– Heli-coil inserts for pressure plate to prevent stripping during clutch replacement
– Factory starter ring gear
