6-Point Rear Lower Brace

The Ultra Racing 6-Point Rear Lower Brace (SKU: UR-RL6-1178) is precision-engineered to enhance the chassis rigidity of the BMW E85/E86 models produced between 2002 and 2008. By stiffening the rear subframe area, this brace significantly improves rear-end stability and traction during cornering, leading to better handling characteristics. Constructed from high-grade steel, the brace features steel plates measuring 4mm to 5mm in thickness and hollow steel tubes ranging from 1.2mm to 1.6mm in thickness. The brace is laser-cut and CNC-bent for precise fitment to factory mounting points, allowing for a straightforward bolt-on installation without the need for drilling, cutting, or any permanent modifications. This brace is specifically engineered for the following applications: BMW E85 (Z4) 2.5 2WD Roadster (2002-2008), BMW E85 (Z4) 2.5 2WD Roadster NO DOOR SWITCH (2002-2008), BMW E85 (Z4) 3.0 2WD Roadster (2002-2008), BMW E85 (Z4) 3.0 2WD Roadster NO DOOR SWITCH (2002-2008), BMW E86 (Z4 3.0 2WD Coupe) (2002-2008), and BMW E86 (Z4 3.0 2WD Coupe NO DOOR SWITCH) (2002-2008). It is crucial to confirm your chassis code, engine variant, and drivetrain match this compatibility list before ordering. The manufacturer also notes that Ultra Racing braces are generally made for non-M Z4 models and may not properly sit with plastic trim on some variants.
