Over time, the rear trailing arm mounts, shock towers, and rear subframe mounting points on the BMW E36 chassis may develop fatigue and structural weaknesses, particularly in vehicles with increased power and upgraded suspension components. This reinforcement plate kit is designed to strengthen these critical areas, reducing the likelihood of metal fatigue and failure. Precision-Engineered for Durability Bull Boost Performance Inc. manufactures these reinforcement plates in-house to ensure the highest quality and fitment. Each plate is CNC plasma-cut from 1/8-inch (.125") thick steel, providing superior strength and durability. Installation Options: Professional welding is recommended for the most secure installation. High-strength epoxy may be used as an alternative for a non-welded application. Shock tower reinforcement plates can be bolted in for ease of installation. Kit Contents: Four (4) subframe reinforcement plates Two (2) rear trailing arm (RTA) reinforcement plates Two (2) shock tower reinforcement plates Additional Information: It is recommended to install new M8-10 self-locking collar nuts when mounting the shock tower plates.
