ACT Flywheel Prolite Subaru STI 2004-2021 / Legacy GT Spec B 2007-2009

This is the ACT Prolite flywheel, which is ACT's lighter flywheel offering with lowest inertia. Prolite flywheels are designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability. Materials are properly distributed for maximum strength, good heat tolerance and rigidity. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.

Dramatically improved engine response and acceleration, mild to moderate gear rattle

Heat-treated forging for strength and toughness, induction-hardened ring gears for maximum life

Quality One piece construction allows less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. No more warped inserts or loose ring gears
