Trailing Arm Outer - Bushing Kit

Eliminate unwanted compliance and unlock the full potential of your ND Miata rear suspension with this Rear Knuckle Bushing Kit. The factory rubber-injected bushings with metal sleeves offer a comfortable ride for the street—but at the cost of performance. Under aggressive driving, these OEM bushings deflect and bind, introducing instability and alignment changes through corners that limit grip and driver confidence. Our kit replaces the soft factory components with Whiteline's synthetic elastomer bushings. This upgrade removes the "mushy" feel from the rear end, eliminates artificial spring rates, and ensures maximum grip and consistent handling at the limit.
