One of the common problems that arises in the E46 M3 is the weakening or cracking of the rear subframe mounting points in the sheet metal chassis. Over time, the loading and unloading of the rear subframe will cause the sheet metal to fail, negatively affecting the handling and power delivery.
The repeated stress placed on the rear subframe mounting points can lead to cracks or weakening of the sheet metal over time. This can compromise the structural integrity of the chassis, impacting the performance of the vehicle.
By welding a set of steel reinforcement plates onto the chassis, the subframe load is distributed over a stronger and larger surface area. This helps prevent future failure by providing additional support and strength to the mounting points.
Our full subframe reinforcement service includes the installation of subframe reinforcement plates, disassembling the rear subframe, suspension, and drive-train components, and prepping, welding, and painting the reinforcement plates onto the chassis. This comprehensive process ensures that the subframe is properly reinforced to prevent any potential issues in the future.
It is strongly recommended to consider subframe reinforcement as a preventative maintenance item for all E46 cars, especially for those who enjoy spirited driving or track use. By addressing this common issue proactively, you can enhance the longevity and performance of your vehicle.
