Overview

The CMP Engineering Stage 3 RACP Brace is a lightweight chassis reinforcement for BMW E46 models.

Constructed from 3mm thick 190MPa yield aluminum, this brace significantly increases torsional chassis rigidity by bracing the rear bulkhead to the front two rear subframe mounts. It requires only two holes to be drilled for installation and weighs just 1.6kg.
Show original supplier description
The CMP Engineering Stage 3 Front Bolt-In RACP Brace is designed to significantly enhance the torsional rigidity of your E46 chassis. This lightweight aluminum brace connects the rear bulkhead to the front two rear subframe mounts, mimicking the structural integrity found in E46 sedans that provided a 33% increase in rigidity over coupes. Constructed from 3mm thick, 190MPa yield aluminum, the brace itself weighs only 1.6kg (3.5 Lb). Its design allows it to fit flush against the rear seats in their upright position, ensuring no compromise to cabin or trunk space. The installation process is simplified, requiring only two holes to be drilled. **Please note:** This Stage 3 brace requires the Stage 2 - E46 Front Weld-In RACP Beam to be installed prior to its own installation. Fasteners for the Stage 3 brace are included.
