Clutch Masters FX400 6 Puck Single Disc Clutch Kit 06-09 Legacy / 04-21 STI | 170% Holding Capacity | High-Performance Clutch Kit
Overview
The Clutch Masters FX400 6 Puck Single Disc Clutch Kit is engineered for Subaru Legacy models from 2006 to 2009 and WRX STI models spanning 2004 to 2021. Designed for enthusiasts seeking extreme-duty street and road or drag racing performance, this clutch kit significantly increases holding capacity by 170%, making it ideal for high-torque applications and aggressive driving styles. The 6-puck ceramic disc configuration offers a rapid engagement that suits drivers who prioritize performance and clutch responsiveness over smoothness.
Built around the Power Plus I heavy-duty pressure plate and a custom sprung ceramic disc, the FX400 system balances durability with street usability.

For Subaru owners pushing their vehicles beyond stock power levels, especially in STI and Legacy platforms, this clutch kit delivers the engagement and durability necessary for spirited street driving and competitive motorsports. While the 6-puck design may produce some clutch chatter during initial engagement, it offers a more aggressive feel preferred by racers and experienced drivers. This clutch is not recommended for stock or near-stock vehicles due to its aggressive nature and ceramic material characteristics.
