E46 Rear Chassis Reinforcement Plates

The E46 chassis, while a capable platform, is known for weaknesses in its rear subframe mounting points, which can crack and fail even with stock bushings. The Garagistic E46 BMW Rear Chassis Reinforcement Plates address this by thickening and reinforcing the chassis metal in these critical areas. This kit is highly recommended for all E46 models as preventative maintenance and is a requirement for any E46 intended for performance driving, track use, or spirited driving. This reinforcement kit is crucial for preventing costly repairs and potential chassis failure. Once the chassis cracks, repair becomes significantly more expensive, and in severe cases, the chassis can become unusable. By reinforcing these points, you safeguard your E46 against common structural issues, especially when paired with stiffer bushings. This kit includes two front mounting point reinforcement plates (right and left), two rear mounting point reinforcement plates (right and left), two spacers, and two square trunk block-off panels. It also includes two M12x1.5 bolts. Professional installation is recommended, and these reinforcements may require welding and potentially minor modifications such as bending or grinding to fit correctly.
