BMR's billet aluminum differential bushing kit for 2015–2017 S550 and S650 Mustang replaces the OEM rubber mounts with CNC‑machined aluminum bushings finished in black. Designed to eliminate differential movement and pinion rise, the kit improves rear stability for street, drag, and handling use. Aluminum construction resists heat and environmental degradation; note that solid mounting may increase NVH compared with rubber.
