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.
