Kartboy Rear Diff Outrigger Bushings - Hard Subaru WRX / STI 2002-2007
The Kartboy Rear Differential Outrigger Bushings for the 02-07 WRX & STi will eliminate alot of excess play associated with the soft stock rear differential bushings under hard acceleration and on/off throttle loads. Most (if not all) of the infamous subaru "clunk" will also be removed after installation of these kartboy bushings. Constructed of durable urethane and made in the USA.
Combined with some other driveline bushings, these really help firm up the car.
