The Fidanza aluminum flywheel for 2006–2012 Lexus IS250 6-speed applications. This billet aluminum flywheel uses 6061-T6 or 2024-T4 construction with a replaceable, heat-treated friction plate and hardened 1050 steel ring gear. It reduces rotating mass—listed as 40–60% lighter than stock—providing lower inertia and quicker throttle response; military-spec fasteners and stepped dowels aid reliability.
