Rear trailing arm bushing reinforcement for the E36. These hard urethane discs are placed on each side of the rear trailing arm bushings to reinforce the soft factory bushings and limit side movement which causes rear steer. We feel all E36 and E46 BMW's will benefit from installation of these discs - this is an easy to install upgrade you can really feel, yet does not affect ride quality. Set of 4 does one car.
Fitment note: These do not fit the Z3 and compact Ti suspension.
