The ACT XACT Prolite flywheel for 2002 Subaru Impreza is ACT's lowest-inertia option, offering the quickest throttle response and strongest acceleration characteristics. Prolite units are intended for road or rally racing and reduce drivability compared with stock. Materials are distributed for strength, heat tolerance and rigidity; the flywheel is serviceable and can be resurfaced, with a one-year warranty.
