The Fidanza aluminum flywheel fits Nissan Skyline R32 (RB25DE) and R33 (RB25DE/RB25DET) applications and serves as a lightweight bolt-on replacement. Built from billet aluminum with a replaceable hardened steel friction plate and ring gear, the flywheel reduces rotating mass—often 40–60% lighter than stock—to free throttle response. It uses stepped dowels on most fits, heat-treated friction surfaces and robust fasteners for reliable installation.
