Clutch Masters 850 Series Street Twin Disc Clutch Kit 02-05 WRX

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 Subaru WRX models from 2002 to 2005, delivering exceptional clamping force and durability for high-performance street and light track use. This twin disc setup combines a sprung ceramic disc with a fiber tuff rigid disc to provide a smooth engagement while handling increased horsepower and torque demands. Designed for enthusiasts who require a reliable clutch that can withstand aggressive driving without sacrificing drivability, this kit is an ideal upgrade over the factory clutch for modified WRX owners.

Clutch Masters applies advanced racing technology to this twin disc system, focusing on strength and consistency. The billet aluminum pressure plate cover is Type 3 hard anodized for durability and features approximately 25% more tensile strength than typical cast covers. This design minimizes flex to just .003 inches, compared to up to .030 inches in cast or stamped units, ensuring that all diaphragm movement is dedicated to clutch engagement and disengagement. The result is a clutch that operates with consistent pedal feel and improved power transfer efficiency.

For Subaru WRX owners, this clutch kit offers a significant performance advantage by increasing the usable friction surface area and clamping force, which translates to better power handling and reduced slippage under load. The Quick Release (QR) pressure plate system further enhances street usability by reducing clutch chatter and noise by up to 50%, making it a practical choice for daily-driven vehicles that see spirited driving or occasional track sessions. This balance of race-inspired engineering and street-friendly operation makes the Clutch Masters 850 Series a standout option for WRX enthusiasts.
