The JB Racing Aluminum Lightweight Flywheel is a high-performance upgrade for your E36 318 or 318ti, dramatically reducing the heavy rotating mass of the stock flywheel. The result? Quicker revs, sharper throttle response, smoother gear shifts, and effortless rev-matching.
Purpose-built for performance on the street, this lightweight flywheel lowers both static weight and Moment of Inertia (MOI). That means your engine spins up faster and uses less energy to turn the flywheel—delivering more usable power straight to the wheels.
Each flywheel is precision-machined from billet aluminum in a single-mass design that mirrors the factory specs, ensuring full compatibility with your original clutch components.* Designed and built in-house on advanced CNC machinery, every JB Racing flywheel is engineered, balanced, and quality-checked at their U.S.-based facility.
Trusted by top-tier race teams nationwide, JB Racing has earned a reputation for exceptional machining and motorsports-grade components. Their BMW flywheels are built to the same exacting standards that professional drivers rely on—far superior to most aftermarket alternatives.
