Clutch Masters 850 Series Street Twin Disc Clutch Kit 02-05 WRX | Twin Disc Design | High-Performance Clutch Kit
Overview
The Clutch Masters 850 Series Street Twin Disc Clutch Kit is engineered specifically for the 2002-2005 Subaru WRX, offering a robust solution for enthusiasts seeking enhanced clutch performance without sacrificing drivability. This twin disc setup combines a sprung ceramic disc with a fiber tuff rigid disc to provide increased clamping force and torque capacity, making it ideal for high horsepower street builds and occasional track use. Designed to fit smaller bell housings, the FX850 kit balances race-grade technology with street-friendly operation.
Clutch Masters focuses on precision engineering and durability, evident in their use of billet aluminum covers that are Type 3 hard anodized for strength and longevity. The billet cover design reduces flex to just .003 inches, significantly less than typical cast or stamped covers, which enhances clutch engagement consistency and driver confidence. Additionally, the Quick Release (QR) pressure plate system ensures smooth, even engagement and reduces clutch chatter by up to 50%, a feature that sets this clutch apart in both street and performance applications.
For Subaru WRX owners, this clutch kit translates to reliable power transfer and improved pedal feel, allowing the engine’s output to be fully utilized without excessive pedal effort. The increased clamping force and expanded friction surface area provide a noticeable improvement in holding capacity, essential for modified engines making higher torque. Whether daily driving or pushing limits on the track, the FX850 delivers a durable and responsive clutch experience tailored to Subaru’s unique drivetrain characteristics.
