ACT XACT Prolite Flywheel ACT600350 for 2000-2009 Honda S2000

600350 is a 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. XACT Flywheel Prolite 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; 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; Recommended for race use; Forged, CNC machined and dynamically computer balanced for smooth high RPM reliability

• "Excellence in Performance", backed by the best one-year warranty in the industry!

Brief Description: The ACT XACT Prolite Flywheel is a lightweight, low-inertia performance flywheel designed for improved throttle response, faster acceleration, and sharper engine feel in the Honda S2000. Part number ACT600350 is engineered for demanding performance applications, including road racing and rally use, where rapid engine response is a priority. Its reduced inertia can improve acceleration while providing the responsive characteristics expected from a competition-oriented flywheel.

Performance Benefits: The ACT Prolite flywheel uses carefully distributed materials to balance strength, heat tolerance, and rigidity. A heat-treated forged construction supports durability, while the induction-hardened ring gear is designed for extended service life. The one-piece design promotes consistent heat transfer from the clutch disc and eliminates concerns associated with loose ring gears or warped inserts. Forged, CNC-machined, and dynamically computer-balanced construction helps provide smooth reliability at high engine speeds. This flywheel is recommended for race use and may produce mild to moderate gear rattle with reduced street drivability compared with a heavier stock-style flywheel.
