Clutch Masters FX500 6 Puck Single Disc Clutch Kit 15-17 WRX | 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 designed for Subaru WRX models from 2015 to 2017. Engineered to deliver a substantial increase in holding capacity—between 200% and 400% over stock—this clutch kit is intended exclusively for competition and track use. It features a solid hub 6 puck ceramic button disc paired with the Power Plus II pressure plate, offering rapid engagement and exceptional heat dissipation for high-performance driving scenarios.
Built with precision and durability in mind, the FX500 system incorporates a hi-leverage pressure plate with heavy-duty straps and dual stacked heat-treated diaphragms. The ceramic friction material ensures outstanding holding power but results in a heavier pedal feel and clutch chatter, characteristics that make it unsuitable for street driving. Clutch Masters’ engineering approach focuses on maximizing clamping force and thermal management to withstand the rigors of drag racing and other motorsport applications.
For Subaru enthusiasts seeking a clutch that can handle extreme power levels and aggressive launches, the FX500 6 puck kit provides a direct and immediate engagement that enhances throttle response and drivetrain control. While this clutch demands a firm pedal and precise operation, it is a proven solution for race teams and serious track drivers who prioritize performance and reliability under high stress.
