The SuperPro front upper inner control arm bushing kit for 1990 Mazda Miata restores suspension geometry and reduces unwanted arm movement to sharpen steering feel. Constructed from SuperPro's proprietary polyurethane and developed in Australia, these bushings resist oils, water and extreme temperatures, run quieter and last longer than rubber, improving tire wear and alignment retention while carrying a lifetime warranty.
