Product Description

The Superpro SPF4185K is a rear trailing arm bushing kit designed for BMW E30 and related chassis platforms. It replaces factory rubber bushings with high-strength polyurethane components to significantly improve rear suspension precision and durability.

By reducing unwanted flex in the trailing arm assembly, this kit helps maintain accurate camber and toe alignment under acceleration, braking, and cornering loads. The result is sharper handling response, improved stability, and more consistent tire wear performance.

The offset bushing design also provides a degree of alignment correction, making it suitable for both restored classic BMW builds and performance-oriented street or track applications requiring improved chassis control.
