Fidanza lightweight aluminum flywheel for 1968–1980 MG MGB 1.8L features a 127-tooth ring gear and a replaceable heat-treated friction plate. Constructed from billet 6061-T6 or 2024-T4 aluminum, these flywheels lower rotational mass by roughly 40–60% compared to stock to improve throttle response and acceleration. The assembly uses military-spec fasteners and offers a bolt-on replaceable friction plate and hardened steel ring gear for durability.
