The ACT Prolite flywheel is even lighter than ACT's Streetlite model. At under 10 pounds, the Prolite is ideal for road racing, autocrossing, or other applications where quick response is paramount. It can take a little getting used to driving with a very light flywheel, but we think the benefits are well worth it.
Note: The light weight of these flywheels may result in additional drivetrain noise. Also, because the engine revs up and down so much faster, the 2.0-liter ECU may get upset and throw a single-cylinder misfire CEL code. (These codes can be disabled using custom ECU programming.) We will not accept any returns because of these conditions.
Tech tip: Flywheel bolts torque to 52.8 ft lbs.
Weighs 9.6 pounds.
Fits all 2002-2005 WRX.
