If you are experiencing rear clunk of your 2002-2007 WRX/STI, you may want to consider a set of Kartboy rear diff crossmember bushings! You will notice improvements on acceleration, deceleration, and these are made out of hard urethane that will reduce deflection and absorb more shock.
These Kartboy bushings are hand made in the U.S.A., and are guaranteed.
