Clutch Masters 725 Series Street Twin Disc Clutch Kit 06-17 WRX | Twin Disc Design | High-Performance Clutch Kit
Overview
The Clutch Masters 725 Series Street Twin Disc Clutch Kit is engineered for Subaru WRX models from 2006 to 2017, as well as select Forester, Legacy, and Baja models. This kit features a 7.25" twin disc setup designed to handle high horsepower and torque levels, making it ideal for enthusiasts who demand strong, reliable clutch performance both on the street and at the track. It includes a steel flywheel and offers a balance between race-level clamping force and manageable pedal effort for occasional street driving.
Built from decades of drag racing experience, the FX725 twin disc clutch system stands out with its billet aluminum cover assembly that is Type 3 hard anodized for durability and strength. This cover exhibits minimal flex—only .003" compared to up to .030" in cast or stamped units—resulting in more consistent clutch engagement and improved driver confidence. The Quick Release (QR) pressure plate system further enhances smoothness and reduces clutch chatter by up to 50%, a unique feature that blends race performance with street usability.
For Subaru owners pushing the limits of their drivetrain, this clutch kit delivers superior clamping force to maximize power transfer without sacrificing drivability. The steel flywheel included is precision-machined from 1045 billet steel and treated with black oxide for corrosion resistance, ensuring durability under demanding conditions. Whether upgrading for spirited street driving or competitive motorsports, this clutch kit provides a robust solution tailored to Subaru’s smaller bell-housing applications.
