ACT XACT StreetLite flywheels are ideal for street or drag race Subaru WRX STIs that require a quick throttle response and maximum straight-line acceleration power. Most stock flywheels are heavy cast iron parts designed for optimum street driveability by soaking up some of the power from the engine and putting it in storage in the form of inertia. Although this may be important for transporting the groceries, this driveability comes at the expense of engine response and acceleration.

Light weight flywheels keep less inertia in storage but the lighter rotating mass provides significantly improved engine response and acceleration characteristics. Until now, most aftermarket flywheels for Subaru WRX STIs presented certain undesirable concessions to the user. Many are too light or fragile for the application, others have reliability issues and all are very expensive.

Finally, ACT offers exactly what Subaru WRX STI performance enthusiasts need: all the benefits of a premium quality light weight flywheel at an affordable price.

ACT XACT flywheels are certified by ACT to meet SFI Spec. 1.1. This makes XACT Flywheels legal for competition when SFI Spec. 1.1 is required or recommended. XACT flywheels come complete with official SFI sticker and serial number as required for certification.

ACT StreetLite Flywheel Key Features:
  • Preferred for street and drag racing.
  • Improved throttle response and acceleration.
  • Extremely durable and good driveability.
  • Very light, with minimal rotational inertia.
  • Made from hot forged chrome-moly steel for extreme strength.
  • 1 year limited warranty.
Note: If you plan on using your Subaru WRX STI for road racing, you may prefer the ProLite flywheel, which is even lighter. For road racing, a lower moment of inertia is more desirable because it allows for quicker throttle response and aids in deceleration, which leads to faster lap times.
