Good write up. I'll need to look into the rear bumper, as mine seems to sit lower than stock, and the mounting hardware looks sad
Rear M-tech2 bumper alignment & gap fix
Finally got to fix my rear bumper. The bumper cover ends were protruding outside on both sides and also had a gap of around 10mm. To fix, I used the 3D printed brackets from trinitygraphicsnc with new clips. The new brackets allow adjustment inwards plus some rotation and are much thicker than OEM so they grab the bumper cover more tight. They reuse the same 10mm nuts.
Installation is straightfortward. Took the 2 large bumper bolts out which I found they were rusted to hell and nearly snapped them which allowed to slide the bumper a bit out to replace the guides. I also removed the inner fender liners to do that (a couple of 8mm screws + 10mm plastic nuts). The fender liners gave me some hard time as the larger 3d guides interfered a bit. I used my heat gun to soften the liner a bit and it went back to place 100%.

Trying to resurrect this thread. I am planning to retrofit an M-Tech style rear bumper on a 323i pre-facelift sedan. Can anyone tell me if the brackets from BMW E46 Upgraded Rear Bumper Brackets will work and needed?
