Clutch Masters FX400 Clutch Kits for a 2018-2021 Subaru WRX Base / Limited / Premium.
170% Increase in Holding Capacity - RACE/STREETThe FX400 System uses the Power Plus I, Hi-Levarage, Heavy-Duty Pressure Plate with a custom and extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 6 or 8 ceramic puck configuration. The 6-puck being the more aggressive setup and 8-puck being the less aggressive. The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more street friendly than solid or rigid designs. This disc is designed for long life, outstanding holding capacity, and rapid heat dissipation.
Features:The FX400 System uses the Power Plus I Pressure Plate with a custom, extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 4 or 6 wing (paddle) configuration, with the 4-wing being the more aggressive setup (please specify which type you prefer). The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more streetable than solid or rigid designs. This disc is designed for long life, outstanding holding capacity, and rapid heat dissipation.
Warning: Due to the solid (no Marcel) friction rivet design, the FX400 disc engages very quickly and may chatter slightly in first and reverse. To help alleviate this problem, we only use premium ceramic friction material.
All stages come as a complete kit including disc, pressure plate, throwout bearing (when applicable), pilot bearing (when applicable), and alignment tool. (Individual components available upon request)
