The Fidanza aluminum flywheel for 2014–2016 Ford Fiesta ST replaces the heavier stock unit with a lower-mass option to free rotational inertia for quicker throttle response. It’s a billet 6061-T6 or 2024-T4 aluminum body with a replaceable, heat-treated friction plate and hardened ring gear. Typical benefits include a 40–60% weight reduction versus stock, lower MOI for faster acceleration and military-spec fasteners for secure attachment.
