The new Competition Clutch Steel Ultra Lightweight Flywheel (STU) for the Subaru WRX, Legacy, Forester & the RB20/RB25 Nissan Skyline models provides a high quality alternative for race only applications. The STU flywheels are manufactured from 4140 Forged Steel and are a one-piece design.
The 4140 Forged Steel material is precisely distributed for maximum strength, lower inertia (reduced mass = increased acceleration), increased heat tolerance, and increased strength. These characteristics prevent ring gear separation, reduce friction surface warpage, and maintain the rigidity of the flywheel. STU flywheels can also be resurfaced for long term durability. CCI flywheels are CNC machined and balanced to better than O.E. specifications.
The Competition Clutch Steel Ultra Lightweight Flywheel (STU) for the RB20 & RB25 Nissan Skyline models with a push type transmission, provides a lighter 10.4lb. flywheel that helps decrease the moment of inertia compared to the factory 22lb. flywheel. This weight reduction will result in better throttle response and quicker acceleration.
Subaru WRX, Legacy & Forester models in particular STU flywheel is recommended for race only applications and may trigger a Check Engine Light (CEL) as this flywheel only weighs 10.45 lbs.
