The SuperPro rear differential mount bushing kit for 1990 Mazda Miata replaces the forward pinion mounts with polyurethane parts that restore accurate differential location and road feel. The design maintains OEM noise and vibration isolation while significantly improving service life over original rubber components. This repair reduces the sluggish, imprecise handling produced by worn mounts and keeps cabin NVH levels close to new-car comfort.
