E28 M5 Aluminum Lightweight Flywheel

Our JB Racing Aluminum Lightweight Flywheel substantially reduces the rotating mass compared to your stock E28 M5 flywheel, allowing your engine to rev quicker, resulting in faster shifting and smoother rev-matching.

JB Racing’s lightweight aluminum flywheels are specifically engineered to boost performance in street-driven vehicles by lowering static weight and Moment of Inertia (MOI). This lighter design demands less energy to spin up, allowing more power to efficiently reach your wheels.

These flywheels are meticulously crafted from premium billet aluminum in a precision-engineered “single-mass” format, closely matching OEM flywheel dimensions to accommodate original clutch components seamlessly.* JB Racing utilizes advanced CNC machinery, ensuring every flywheel undergoes precise design, machining, assembly, balancing, inspection, and packaging processes.

JB Racing is recognized nationwide for exceptional machining quality, trusted by many professional motorsports teams for engine and drivetrain components. Their BMW flywheels uphold this same professional standard, exceeding typical aftermarket alternatives.

Standard features include:

• CNC-machined flywheel, zero-balanced for minimal vibration
• Replaceable hardened steel clutch surface secured by bolts (not rivets)
• Heli-coil threaded inserts prevent stripping during clutch replacements
• Factory-spec starter ring gear
• Hardened steel gaul plate protects flywheel surface from bolt damage
• Complete hardware package including flywheel bolts, pressure plate bolts, and captive 10mm dowel pins
