The ACT XACT Prolite flywheel is the lightest ACT offering for the 2005 Subaru Legacy, optimized for lowest inertia to improve throttle response and acceleration. Prolite flywheels favor road or rally racing use with reduced drivability; materials are distributed for strength, heat tolerance and rigidity, and the unit is serviceable and resurfaced without needing additional parts.
