Fidanza aluminum flywheel for 2003–2004 Saturn Ion. The lightweight aluminum construction reduces rotating mass—listed as 40–60% lighter than stock—for quicker acceleration and lower inertia. Features include a heat-treated friction plate, replaceable hardened 1050 steel ring gear, billet aluminum body options, military-spec fasteners and a bolt-on replaceable friction surface for long-term serviceability.
