The SuperPro upper control arm camber-adjustable bushing kit for 1990 Mazda Miata uses a double-offset design to introduce positive caster and sharpen handling. This change improves directional stability, steering return and overall cornering behavior without accelerating tire wear. Made from engineering-grade polyurethane, the kit resists oils and temperature variation while delivering longer service life and more precise steering feel compared with worn rubber bushings.
