Clutch Masters FX350 Single Disc Clutch Kit 02-05 WRX / 91-94 Legacy | 110% Holding Capacity Increase | Street/Race Clutch Kit
Overview
The Clutch Masters FX350 Single Disc Clutch Kit is engineered for Subaru WRX models from 2002 to 2005 and Legacy models from 1991 to 1994. Designed for serious street enthusiasts and weekend racers, this clutch kit offers a significant upgrade in holding capacity—approximately 110% more than stock—making it ideal for highly tuned naturally aspirated engines, medium-boost turbo or supercharged setups, and even vehicles running up to 100 horsepower on nitrous oxide. It balances aggressive engagement with durability, providing a performance edge without sacrificing drivability.
At the core of the FX350 system is the Power Plus I heavy-duty pressure plate paired with Clutch Masters’ Fiber-Tough friction material. This combination is engineered to close the traditional gap between clutch longevity and performance, delivering a clutch that can handle increased power loads while maintaining a reasonable service life. The kit includes a heavy-duty sprung hub and premium components such as OEM or better release and pilot bearings, ensuring reliable operation under demanding conditions.
For Subaru owners, this clutch kit translates to enhanced throttle response and improved power transfer, especially important for vehicles with upgraded cylinder heads, cams, or forced induction. While the engagement is more aggressive and may produce some chatter, this is a tradeoff many enthusiasts accept for the increased holding power and track-capable performance. The FX350 is a practical choice for those who want a clutch that performs well on the street but can also handle spirited driving and occasional track use.
