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 clutch performance for high horsepower and torque applications. Designed as an 8.5” twin disc system, this clutch kit is ideal for racers and serious enthusiasts who demand reliable power transfer and consistent pedal feel under extreme conditions. Whether on the track or a high-performance street setup, this clutch kit offers the durability and engagement needed to handle aggressive driving without compromise.
Built with precision and racing technology, the FX850 twin disc clutch features a billet aluminum cover that is Type 3 hard anodized for superior strength and minimal flex. This design significantly reduces clutch chatter and improves pedal consistency by eliminating flex in the pressure plate cover. Clutch Masters’ unique Quick Release (QR) system further enhances smooth engagement and reduces internal noise by up to 50%, making it a standout choice for drivers who want race-level performance with street-friendly operation.
For Subaru WRX owners, this twin disc clutch kit translates to improved drivability and confidence when pushing the limits. The increased clamping force and expanded friction surface area ensure that all engine power is effectively transferred to the drivetrain, minimizing slippage and maximizing acceleration. The option to upgrade to the DLX series adds inherent damping for shock load protection, ideal for daily-driven cars with high horsepower or race cars requiring extra drivetrain durability.
