JCE Racing carries Flywheels from ACT, Fidanza, Spec Clutch, Clutch Masters, Exedy and many more. A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have an inertia called the moment of inertia and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed.
