The ACT SB11-XTR6 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 solid 6 pad, segmented disc which grabs very quickly and aggressively both from a stop and in between shifts. It is not recommended for pure street applications. To finish off the full kit, the alignment tool and a new release bearing/throwout bearing are included in the Subaru WRX clutch kit.
