This kit features a heavy duty pressure plate and full-face Kevlar lined disc for smooth engagement & long life. Recommended for 06-07 WRXs with basic bolt-on modifications, ECU tuning and small-medium turbo and fuel upgrades. This clutch offers comparable torque capacity as the FX100, but provides exceptionally smooth engagement & extended life, due to the full-face Kevlar disc. This clutch is designed for the daily driver that desires smooth & effortless transitions as well as more torque holding capacity. Kevlar clutch discs require a strict 500-750 mile break-in period. See manufacturer's literature or call for more information.
