The ACT SB11-XTSS clutch kit for the Subaru WRX 2006+, including the new 2015+ FA20DIT WRX, is a full replacement system for your WRX clutch setup. It includes the flywheel as well as all other components to make install a breeze. The kit features an xtreme duty pressure plate which grabs much harder than stock, holding much larger amounts of power and torque than stock. This pressure plate will require a good deal more pedal effort to disengage making it more suitable for higher performance applications ony. This kit also comes with a sprung full face disc which grabs similar to a stock disc and will promote more consistent feel and grab. This is recommended for street use but can easily be used for mild track days. To finish off the full kit, the alignment tool and a new release bearing/throwout bearing are included in the Subaru WRX clutch kit.
