Clutch Masters FX300 Single Disc Clutch Kit 03–06 Baja / 13–17 Crosstrek / 97–12 Forester / 94–21 Impreza / 90–14 Legacy | 110% Increased Holding Capacity | Heavy-Duty Street Clutch Kit
Overview
The Clutch Masters FX300 Single Disc Clutch Kit is engineered specifically for Subaru enthusiasts who demand a robust and reliable clutch solution for highly tuned street vehicles. Designed to handle increased torque from naturally aspirated engines with cylinder head modifications, medium-boost turbo or supercharger setups, and up to 100 horsepower from nitrous oxide, this clutch kit offers a significant upgrade over OEM components. It is ideal for owners of the 2003–2006 Baja, 2013–2017 Crosstrek, 1997–2012 Forester, 1994–2021 Impreza, and 1990–2014 Legacy models seeking enhanced holding capacity without sacrificing street drivability.
At the core of the FX300 system is the Power Plus I Heavy-Duty Pressure Plate paired with a steel-backed segmented Kevlar disc. This design philosophy focuses on maximizing torque capacity while maintaining smooth engagement and long service life. The segmented Kevlar friction material is non-abrasive, preventing damage to flywheel and pressure plate surfaces, which contributes to extended durability. Clutch Masters’ engineering approach balances increased pedal effort with everyday usability, making it a standout option for street-driven Subarus with performance upgrades.
For Subaru owners, this clutch kit translates to confident power delivery and improved drivetrain reliability under demanding conditions. The FX300’s enhanced holding capacity supports aggressive tuning stages, allowing enthusiasts to push their vehicles further without clutch slip. While it requires a 500-mile break-in period, the result is a clutch that offers positive engagement and longevity, tailored to the unique needs of Subaru’s diverse lineup of performance and utility models.
