BMW E46 Rear Frame-to-Subframe Reinforcement

The BMW E46 has some problems with the factory chassis. The rear subframe mounts at 6 points through sloppy rubber bushings. Over enough time the floor can crack at these points, so we sell reinforcement kits to repair that, and we are well versed in those repairs.  We've seen some E46 cars that sustained serious damage to the rear trunk floor and subframe mounting area. For those cars, a "little extra" reinforcement is not a bad idea. Which is why we created these trunk side "frame-to-floor" reinforcements. We make these 100% in-house and can almost always ship the same day you order - let us know if you are in a rush and we can make room on our CNC  plasma table.  The first install was on a 2003 E46 M3 that had extensive cracking, and this is what the customer wanted. We have instructions below on how to install these - it takes cutting, welding, painting, and more. This is not for the novice mechanic - you need a fabricator to do this job right.  The two CNC cut and bent steel pie
