Kartboy Rear Differential Outrigger Bushings Hard Subaru WRX / STI 2002-2007
KB-003-DIFF-H
The Kartboy Rear Differential Outrigger Bushings for the 02-07 WRX & STi will eliminate a lot of excess play associated with the soft stock rear differential bushings under hard acceleration and on/off throttle loads and are designed to eliminate the hard clunk you experience when shifting hard and fast in your Subaru.
Often called rear diff bushings these parts actually sandwich above and below the forward outriggers for the rear subframe. Please note, that there will be an increase in NVH with these, but they do help considerably with eliminating the clunk from the rear end and tightening up the feel of the rear of the car. Please note, this is the race stiffness so these will create more NVH than the comfort versions
