Clutch Masters Aluminum Flywheel for the 2004 – 2021 Subaru WRX STI
When upgrading your Subaru with one of Clutch Masters Clutch kits, or any OEM style clutch kit, a brand new aluminum flywheel is the perfect addition. Save time waiting for a shop to resurface your flywheel, with Clutch Masters inserts just being a few bolts you can have a brand new friction surface in a matter of minutes.
This flywheel will greatly reduce rotating mass and free up HP. Fully made in America and is best paired with one of Clutch Masters FX100 – FX500 Clutch kits for optimal performance or use with any OEM style clutch kit. Every Clutch Masters flywheel is proudly designed and manufactured in-house. Flywheels are first designed in CAD and are then precision CNC machined in house in one of their Haas CNC lathes out of 6061 aluminum or 1045 steel billet cores. After machining, the flywheel is zero balanced to ensure it is evenly weighted on all sides and spins 100% true. Each aluminum flywheel is Type 3 Hard Anodized for the ultimate in durability and protection of the aluminum. The flywheel is then assembled by a Clutch Master Craftsman, double checked for imperfections and tolerances, and is then ready to be paired with your OEM clutch kit or one of Clutch Masters FX100-FX500 single disc clutch kits.
All flywheels are SFI 1.2 Certified for use in motorsports.
