ACT XACT Prolite Clutch Flywheel, 2002-2021 Subaru Impreza WRX STI | 600240

The ACT 600240 XACT Prolite flywheel is ACT's lightest flywheel offering with the lowest rotational inertia, designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing and have reduced drivability compared to a Streetlite. One-piece chromoly construction reduces the chance of failure and provides uniform, efficient heat transfer from the clutch disc. Includes ACT pilot bearing PB1004.
