Summarized by Shop
Rear subframe cracking is one of the most well-known failure points on the E36 chassis. As grip, power, and suspension stiffness increase, the factory sheet metal around the rear subframe mounting points is forced to carry loads it was never designed for. Over time, that stress concentrates at the mounting pockets and leads to cracking or
