Exedy Lightweight Flywheel 2004-2021 STI

EXEDY Lightweight Flywheels are engineered for light to moderately tuned racing cars, offering the perfect balance of low weight, low inertia, and high thermal capacity. Ideal for drag racing, autocross, rally events, and spirited street driving, these flywheels are crafted to optimize engine response and reduce rotational mass.

Many models feature enhanced airflow designs to improve clutch cooling under extreme conditions. The ring gear is integrated into the flywheel, unlike aluminum flywheels where the pressed-on ring gear can separate due to differing expansion rates between steel and aluminum.
