Product Details

Most stock flywheels are heavy cast iron and are designed for optimum driveability by storing some of the engine's power in the form of inertia. ACT's XACT flywheels provide significantly improved engine response and acceleration without compromising driveability. XACT flywheels are lighter but designed for strength and affordability.


  • Lightest ACT Flywheel
  • Best throttle response, lowest inertia
  • Super rigid precision-made and dynamically balanced
  • Recommended for road and rally racing
  • Mazda RX-8 Includes Counterweight 04
  • 13.4 lbs

  • Images used may be generic. Actual product may vary.
