2006-2026 Subaru WRX

The ACT XACT Prolite Flywheel (600895) is engineered for racers and performance enthusiasts who demand maximum throttle response and rapid acceleration. As ACT’s lightest flywheel offering, the Prolite series delivers ultra-low rotational inertia, allowing the engine to rev faster and respond instantly to driver input.

Constructed from forged chromoly steel and precision CNC-machined, this flywheel is designed for strength, durability, and consistent performance under extreme conditions. Material mass is strategically distributed to maintain rigidity and excellent heat tolerance while minimizing overall weight. At just 8.5 lbs, the Prolite flywheel is ideal for road racing, rally racing, and track-focused builds, where performance outweighs comfort.

The one-piece construction eliminates common failure points found in multi-piece designs, ensuring uniform heat transfer and long-term reliability. ACT flywheels are also fully serviceable and resurfaceable, extending their lifespan without requiring replacement components.

⚠️ Note: This flywheel is intended for race use and may result in reduced drivability, including mild to moderate gear rattle.
