BMW M3 SUBFRAME TO BODY RE-INFORCEMENT E46
It's not uncommon for BMW M3 or other modified E46 chassis vehicles to crack or tear the vehicle body at four spots where the rear subframe (differential and rear suspension assembly) bolts to the body and trunk floor.
This problem is also more likely to occur if the vehicle has oversize tires or is raced or tracked. It's best to reinforce this area before a crack begins. Hard launches or clutch dumps could tear the entire differential and suspension from the vehicle if cracked mounts are left unrepaired.

How to reinforce BMW M3 / E46 rear suspension area
This customer is preventing the problem from developing even before cracks started on his 2003 M3. This car has oversize high performance tires and other chassis improvements that would make it a prime candidate for subframe mount failure and cracking. We are going to TIG weld the reinforcement brackets in place. TIG (tungsten, inert gas) welding is preferred in this situation as we will be welding a thick piece of steel to a thin piece of sheet metal. It can be done with a MIG welder, but the strength and appearance of the TIG weld would be almost impossible to duplicate even with the most experienced welder.
The slot in the center of the reinforcing plate is to strengthen the center of the reinforcement. In this area, the first layer of the factory sheet metal needs to be cut or ground through so the weld can properly penetrate the thicker and stronger under layers of the unibody structure of the vehicle. Clean and paint the welded area inside and out.
