Differential bushings can completely transform the feel of your BMW, depending on what you go with. While you may want to plan for some additional NVH and gear whine transmitted through your bushings, especially if you go with solid bushings. We offer a wide selection of differential - from solid to polyurethane to stock replacement differential bushings, we have what you need to turn your car into what you desire.
