ACT StreetLite Flywheel - 2006-2021 Subaru WRX

Materials are properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity. ACT's Streetlite flywheels are preferred for street or drag racing. XACT flywheels are lighter, stronger and safer than stock cast flywheels to meet the needs of both the enthusiast and hard core racer. One piece construction allows less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. ACT heat treats the entire forging for strength and toughness and induction hardens the ring gear for longest gear life. ACT's XACT flywheels are certified as meeting SFI Specification 1.1. XACT flywheels are legal for competition in all racing organizations where SFI certification is required. Improved engine response and acceleration with lightweight design 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 All flywheels are CNC machined and dynamically computer balanced for super smooth high RPM reliability
