BMW E90 E91 E92 Rear Upper Strut Brace

The BMW E90 E91 E92 Rear Strut Brace is a steel chassis reinforcement bar designed to improve rear-end rigidity and reduce suspension tower flex during cornering and demanding driving conditions.

By connecting the two rear suspension towers, this brace helps distribute loads across the rear body structure, reducing unwanted movement and supporting more consistent chassis stability, handling and suspension response.

Designed for BMW E9x 3 Series performance builds, drifting, track days and motorsport applications, this rear strut bar provides additional reinforcement to the rear suspension mounting area.

Manufactured from steel using MIG/MAG welding, the brace features laser-cut and CNC-pressed mounting brackets. A black powder-coated finish provides additional surface protection and a clean appearance.
