Suspension bushings for the E46 (non-M), X3 and Z4 Differential. Improves feedback to the driver. The harder these bushings are, the less power is lost when pushing the bushings, but also transmits more vibration and noise. This is somewhere between urethane and aluminum. These bushings last longer than the rubber oem bushings. Intended for motorsport use.
Concerns a set of 3 bushings, good for 1 car.
Fits all E46, X3 (E83) and Z4 (E85, E86) except M3 (CSL) and Z4M.
