The ACT SB11-HDSS 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 a heavy duty pressure plate which grabs harder than stock, allowing it to hold more power than stock without slipping. 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.
