The Fidanza 8 lb aluminum flywheel for 1990–1993 Mazda Miata replaces the heavier stock unit to reduce rotating mass and improve throttle response. Built from billet 6061-T6 or 2024-T4 aluminum with a replaceable hardened 1050 steel ring gear and a heat-treated friction plate, it uses military-spec fasteners and stepped dowels for reliable installation while significantly lowering moment of inertia for quicker acceleration.
