The ACT XACT Streetlite Flywheel, part number ACT600550, is engineered to deliver sharper engine response and improved acceleration compared with a factory-weight flywheel. Its reduced rotational mass helps the engine rev more quickly while maintaining the strength, heat tolerance, and rigidity required for dependable street and drag racing performance. This flywheel is designed for Mitsubishi Lancer applications and offers a balanced combination of performance, durability, and everyday drivability.

ACT manufactures the Streetlite flywheel from a heat-treated forging and CNC machines it for precise fit and consistent performance. The one-piece construction promotes uniform heat transfer from the clutch disc while eliminating common failure points associated with loose ring gears or warped inserts. An induction-hardened ring gear is built for extended service life, and the flywheel is dynamically computer balanced for smooth, reliable operation at high engine speeds. The flywheel is also serviceable and can be resurfaced without requiring additional replacement parts.
