SuperPro Rear Trailing Arm Camber & Toe Adjustable Bushing Kit - Select BMW 1984-2002 (SPF4185K)

Fits select 1984-2002 BMW 318, 323, 325, M3, and Z3 models.

The SuperPro SPF4185K Rear Trailing Arm Bushing Kit is engineered to resolve the inherent lack of factory adjustment in BMW semi-trailing arm suspensions. This kit utilizes an offset bushing design to provide 0.5 to 1.0 degrees of camber and toe adjustment, allowing you to return a lowered vehicle to OEM alignment specifications or dial in a custom setup for improved performance. These bushings replace the high-compliance factory rubber components to eliminate unwanted suspension geometry changes under heavy cornering and acceleration.

Formulated from SuperPro's specialized polyurethane, these bushings are designed to withstand harsh road conditions while maintaining factory-level noise, vibration, and harshness (NVH) isolation. By reducing trailing arm deflection, this kit prevents irregular tire wear and restores the precise, predictable handling characteristics expected of a classic BMW chassis.
