Clutch Masters FX500 6 Puck Single Disc Clutch Kit 06-14 WRX / 07-12 Legacy | 200-400% Increased Holding Capacity | Race-Only Clutch Kit
Overview
The Clutch Masters FX500 6 Puck Single Disc Clutch Kit is a race-focused clutch system engineered for Subaru WRX and Legacy models from 2006-2014 and 2007-2012 respectively. Designed specifically for high-performance and motorsport applications, this clutch kit delivers a substantial increase in holding capacity—between 200% and 400% over stock—making it ideal for drivers pushing their Subaru to the limits on the track. This kit is not intended for street use due to its aggressive engagement characteristics and heavy pedal effort.
Built around the Power Plus II Pressure Plate and a solid hub 6-puck ceramic button disc, the FX500 system emphasizes rapid heat dissipation and exceptional clamping force. The pressure plate features a hi-leverage design with precision heat-treated diaphragms and heavy-duty straps, ensuring durability under extreme conditions. Clutch Masters’ engineering approach focuses on uncompromising race performance, with components designed to withstand the rigors of drag racing, road course, and other competitive environments.
For Subaru enthusiasts seeking a clutch that can handle significant power upgrades and aggressive driving styles, the FX500 kit offers reliable engagement and durability. The solid hub design eliminates disc hub flex, providing instant clutch response and minimizing slippage during high torque loads. While the ceramic puck disc produces some clutch chatter and requires heavy pedal pressure, it delivers the precise engagement needed for race applications. This clutch kit is a critical upgrade for Subaru WRX and Legacy owners who demand uncompromising performance on the track.
