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 a purpose-built performance clutch system designed for the 2006-2017 Subaru WRX and compatible Subaru models including the Baja, Forester, and Legacy. This kit features a 7.25" twin disc setup engineered to handle high horsepower and torque outputs typical of race-prepped engines, especially those with smaller bell housings common in drag racing applications. It includes a steel flywheel and offers two available stages tailored for different driving needs: the “Street and Race” stage with a ceramic and fiber disc combination, and the “Race” stage with dual ceramic discs for maximum performance.
Clutch Masters applies decades of drag racing experience to the FX725 design, focusing on minimizing rotational mass while maximizing clamping force and durability. The billet aluminum cover is hard anodized for strength and rigidity, reducing flex to just .003" compared to up to .030" in cast or stamped covers. This precision engineering ensures consistent clutch engagement and improved pedal feel, critical for drivers demanding reliable and repeatable performance on the track.
For Subaru enthusiasts pushing their WRX platforms to the limit, this twin disc clutch kit delivers exceptional holding capacity without excessive pedal effort. The Quick Release (QR) pressure plate system further enhances drivability by reducing clutch chatter and noise by up to 50%, making it a viable option for occasional street use while maintaining race-ready performance. This clutch kit is ideal for those seeking a durable, high-performance drivetrain upgrade that translates directly to improved power transfer and confidence behind the wheel.
