The ACT XACT Prolite flywheel is a lightweight Prolite option built for faster throttle response and improved acceleration. Intended for road and rally use where lower inertia is desired, it redistributes material for strength, heat tolerance and rigidity. Serviceable and resurfacing-capable, the Prolite prioritizes quick engine response at the cost of reduced low-speed drivability compared with heavier flywheels.
