Clutch Masters FX300 Single Disc Clutch Kit 06-14 WRX / 07-12 Legacy | 110% Increased Holding Capacity | Street Performance Clutch Kit
Overview
The Clutch Masters FX300 Single Disc Clutch Kit is engineered for Subaru WRX and Legacy owners seeking a robust upgrade for highly tuned street vehicles. Designed to handle increased power levels 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 delivers reliable engagement and durability for spirited driving. It is ideal for enthusiasts who want a strong, street-friendly clutch without sacrificing drivability.
Built around a heavy-duty pressure plate and a steel-backed segmented Kevlar disc, the FX300 system emphasizes longevity and torque capacity. The segmented Kevlar friction material provides a non-abrasive surface that protects the flywheel and pressure plate from scoring, while the sprung hub design helps absorb drivetrain shock for smoother operation. Clutch Masters’ engineering approach balances increased holding power with manageable pedal effort, making it a standout option for street use where reliability and comfort are paramount.
For Subaru owners, this clutch kit offers a significant upgrade over OEM components, supporting aggressive tuning without the harsh engagement typical of race-oriented clutches. The FX300’s design ensures consistent performance and extended service life, provided proper break-in and installation procedures are followed. This makes it a practical choice for WRX and Legacy drivers who demand more from their drivetrain while maintaining everyday usability.
