These BMW E46 Rear Subframe Reinforcements weld directly onto the chassis – properly reinforcing the subframe mounting points to eliminate the possibility of a failure. An E46 rear subframe reinforcement kit is the only solution to prevent cracking and/or tearing of the sheet metal, caused by torque loads traveling up into the chassis through the inadequate mounting points. Those cars that are swapped, tracked and/or raced are guaranteed to experience a failure – prevent it with our E46 rear subframe reinforcement kit!
Despite the beliefs of some, all E46 3-series BMW’s are prone to cracking at and around the rear subframe mounts. No matter the shape, model or way it is driven, subframe cracks are inevitable. The company began in late 2016 to answer the growing problem of E46 BMW RACP/subframe cracks and failures. After discovering significant cracks in our low mileage E46 M3, we put our engineering abilities to the test and began developing what is now a comprehensive range of CMP reinforcement products for E46 BMW’s.
- Owners of the BMW 3 Series (E46 models) have been reporting cracks and damage in the rear subframe area of their vehicles. The issue was also common on the earlier 3 Series models and unfortunately, have reoccurred with the E46 from 1999-2006. This issue specifically appears in the rear mounting.

This is the floor or body of a E46 that the rear subframe and suspension is bolted to. Damage can best be seen.
Our race-proven E46 rear subframe reinforcements are the thickest on the market and are engineered to properly reinforce the failure-prone mounting points. Unlike other kits, these E46 rear subframe reinforcements strengthen the area correctly, by utilizing extra-thick steel which is designed to precisely cover only the surface area of the chassis that is vulnerable to drivetrain torque loads. This provides for both stronger chassis mounting points AND an easier installation!
Precision CNC laser cut and bent. Set of four reinforcement plates and two spacers. Professional installation recommended – welding required.

Ok so here are photos of the repair done to my BMW. The car is a 2000 323ci, 5sp, 170k miles, and lowering springs, not gonna mention what kind its not their fault, also a stage 2 clutch with light weight flywheel. The vehicle was in over in really great shape and well maintained.
Bmw E46 Subframe Cracking Noise
The repair process wasn't by no means easy. While i didn't do the welding. With some help did the removal of the actual subframe its self. This i think could be done by just about anyone with some friends. If you have every done a clutch or removed an engine you can remove the subframe. First thing is to remove the exhaust and heat shields. Then drop the drive shaft or remove just the rear section like we did. After that its just a mater disconnect the e-brake cables the 2 brake lines and the 3- sensor leads. Undo the the 6 trailing arm bolts and remove the bottom shock bolt and take out the coil springs. Then you can remove the four blots that hold the rear crossmember and then the 4 subframe bolts. Use a jack to support the subframe. You need to keep it level or the front supports will get held up on the studs... So just be-careful and take your time...
So after everything was cleaned up. It was time to weld the mount back in at the top and then the weld all the tears back together up underneath. This is the only way to know that all safety precautions are taken The top and bottom must be welded and made sure to align with all other mounts. If this is not done then you could risk that chance of not being able to remount the subframe. Here is the access hole to the top and what the all the tears look like after they were welded back together.
After all that was done the fabricator (not me) had made a custom plate out of 16g steel to put over this to help distribute the force evenly over the repair. We also had drilled several holes into this plate for rosetta welds to help with the attachment of the plate.
