CMP E46 Subframe/RACP Reinforcement Plate Kit


This kit is designed to repair & reinforce the rear subframe mounts of any E46 3 series BMW. This plate kit was specifically engineered to offer the highest level of rigidity and strength possible providing greater coverage and better stress distribution than any other plate kit on the market!

This kit is laser cut from 2mm zincanneal for corrosive resistance and CNC brake press folded for precise angles and fold centre lines offering the best fitment over any reinforcement plate available!

Every reinforcement plate kit purchased from CMP Auto Engineering includes a very comprehensive 18 page, spiral bound installation manual detailing each step of the installation process over 63 images. This manual details not just how to install the plates but how to locate, analyse and repair common failure points  throughout the Rear Axle Carrier Panel (RACP) structure. Our goal is to ensure that every repair is permanent and reliable. This kit is suited to both experienced specialists and DIY repairers.

(Fits all E46 3 series variants).

This kit was developed over many months with multiple revisions to optimise the design as much as possible and ensure perfect fitment unlike any other.

The key design philosophy for this kit was to maximise rigidity, coverage and correct stress distribution as much as possible  away from key problem areas known to cause secondary failure. The design incorporates strategically positioned weld locations through original structural links to better integrate into the structure and provide a more direct transfer of stress rather than depending on just the sheet metal about the perimeter to avoid introducing new stresses.

For those with higher power variants or modified E46 3 series BMW’s, CMP Auto Engineering recommends additional structural reinforcement in addition to underside reinforcement plates to address additional problem areas and provide a complete, comprehensive peace of mind solution.
