The ACT Streetlite flywheel is constructed from strong-but-light chromoly steel, and it's around ten pounds lighter than stock. It is durable and thick enough to be resurfaced if necessary.
The ACT Prolite flywheel is even lighter than the Streetlite. It's 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. We will not accept any returns because of these conditions.
Remember to torque flywheel bolts to 55.3 ft-lbs on the STi.
Fits all 2004-2021 STI.
Weighs 11.1 pounds.
