The Fidanza aluminum flywheel for 2001–2003 Mazda Protege 2.0L replaces the stock unit with a lighter, high-performance alternative to free rotational mass and improve throttle response. Constructed from billet-grade 6061-T6 or 2024-T4 aluminum with a heat-treated friction plate, it offers a replaceable hardened 1050 steel ring gear and military-spec fasteners. At roughly 40–60% lighter than stock, it lowers moment of inertia for quicker acceleration while remaining bolt-on serviceable.
