The SuperPro rear differential center support bushing kit for 2006 Mazda MX-5 Miata (motorsport, higher durometer) reduces deflection of the OEM rubber mount under changing loads to produce faster, more direct throttle response and quicker cornering reactions. The higher durometer sharpens responses but may slightly increase NVH compared with the street version. It offers a lifetime warranty and extended service life over the factory part.
