The Ground Control Street Stability Kit for E36 / E46 models is a self-lubricating plastic product designed to limit toe changes in the rear suspension without adding any unwanted noise. This kit is a Ground Control Original, featuring a simple installation process.
The kit supplements the stock rear bushings and comes with enough pieces for both sides. Although a rear toe alignment may be necessary since the rear bushings may have already shifted, the pieces are cleverly manufactured to restrict toe changes without producing any squeaks, clunks, or groans.
