Clutch Masters 850 Series Race Twin Disc Clutch Kit 02-05 WRX | High Clamping Force | Twin Disc Clutch Kit
Overview
The Clutch Masters 850 Series Race Twin Disc Clutch Kit is engineered specifically for the 2002-2005 Subaru WRX, delivering exceptional clamping force and durability for high horsepower and torque applications. Designed for racers and serious enthusiasts who demand consistent engagement and superior power transfer, this twin disc system offers a significant upgrade over stock clutches. It is ideal for track use as well as aggressive street driving where clutch performance and reliability are critical.
Built with precision and racing technology, the FX850 features a billet aluminum pressure plate that is Type 3 hard anodized for strength and longevity. The cover assembly’s minimal flex design ensures that all clutch actuation force is efficiently applied to engage and disengage the clutch, resulting in improved pedal feel and consistent operation. Clutch Masters’ unique Quick Release (QR) system reduces clutch chatter and noise by up to 50%, making this race-level clutch more manageable for street use without sacrificing performance.
For Subaru WRX owners, this twin disc clutch kit means harnessing your engine’s full potential with confidence. The increased friction surface area and clamping force translate to better power delivery and less slippage under load, essential for modified engines or those pushing the limits on the track. The kit also offers upgrade paths such as the DLX series for enhanced damping, providing additional drivetrain protection and smoother engagement for daily-driven high horsepower builds.
