Clutch Masters 725 Series Race Twin Disc Clutch Kit 06-17 WRX | High Clamping Force | Twin Disc Clutch Kit
Overview
The Clutch Masters 725 Series Race Twin Disc Clutch Kit is engineered specifically for Subaru WRX models from 2006 to 2014 and select Legacy models from 2007 to 2012. Designed for high-performance applications, this 7.25" twin disc clutch system excels in drag racing and high-horsepower builds where maximum clamping force and durability are critical. It offers a robust solution for enthusiasts seeking to handle extreme torque loads while maintaining manageable pedal effort.
Built with decades of drag racing expertise, the FX725 clutch kit features a billet aluminum cover assembly that is Type 3 hard anodized for exceptional strength and minimal flex. This precision-machined cover delivers approximately 25% more tensile strength than typical cast units, reducing flex to just .003 inches compared to .030 inches in competitors. This rigidity ensures consistent clutch engagement and disengagement, improving driver confidence and control during aggressive launches and shifts.
Available in two stages—“Street and Race” with a ceramic and fiber disc combination, and “Race” with dual ceramic rigid discs—the FX725 balances track-ready performance with occasional street usability. The kit’s quick release pressure plate system reduces clutch chatter by up to 50%, providing smoother operation without sacrificing the aggressive engagement needed for racing. For Subaru owners pushing their WRX or Legacy to the limits, this clutch kit delivers the strength and responsiveness required to fully exploit their engine’s power potential.
