Clutch Masters chromoly-steel flywheel for the Subaru WRX are engineered to be driver friendly with minimal gear rattle which is increased when too light of a flywheel is utilized. The light weight flywheel offers a much quicker throttle response without compromising any bottom end torque which can be reduced when using too light of a flywheel. Clutch Masters light weight flywheels also help to eliminate any turbo-lag which is produced with a heavy flywheel. We recommend the chromoly-steel flywheel for street applications and aluminum flywheel for only race applications. Clutch Masters Flywheels are SFI Certified meeting performance and safety standards for the automotive and motorsport industry.
Note:
If you have a 2005-2009 Legacy GT and are installing a WRX Clutch you need to use this flywheel.
