Exedy makes the OEM clutch on your Subaru, and it's not a bad clutch, either, so you know these folks know their stuff.

Compared to the stock-replacement clutch, Stage 1 upgrades to a heavier pressure plate, with a full-face organic disc -- note that this will lead to more chatter and less-smooth uptake than the stock replacement clutch. 

Rated to hold approximately 278 ft/lbs of torque, measured at the wheels.

Fits all 2002-2005 WRX.
