Seems Legit Garage - High-Clearance Subframe Braces

BMW E8X / E9X Chassis-to-Subframe Brace Kit
(Direct Replacement for BMW 33326784315 & 33326784316 and 33326766053 & 33326766054)

Looking to clear wider tires without compromising rear-end stability? Our Chassis-to-Subframe Brace Kit is designed for BMW E8X and E9X chassis to increase inboard tire clearance while maintaining essential subframe rigidity — a perfect upgrade for street, track, and drag applications.

This kit replaces OEM subframe support brackets BMW 33326784315/33326766053 (left) and BMW 33326784316/33326766054 (right) with low-profile, high-strength billet aluminum pieces that also are able to retain the factory underbody tension strut. This is also a great place to mount a diffuser.

The design allows for better clearance around the inboard wheel/tire area, making it especially useful when fitting wider drag radials or high-grip track tires with a rounder shoulder profile.

Tension Struts are used on E8X and E92 models. 

Key Features:

• Compatible with all BMW E8X and E9X chassis (1-Series and 3-Series)

• Direct replacement for OEM part numbers: 33326784315 (Left) and 33326784316 (Right)

• Improves inboard tire clearance for wide wheel/tire setups

• Retains OEM underbody tension strut attachment for proper chassis rigidity

• Helps stabilize subframe under hard braking, acceleration, and cornering loads

• CNC-machined from billet 6061 aluminum

• Black anodized finish for corrosion resistance 

• Includes left and right brace brackets and required hardware for installation

Perfect for anyone running aggressive fitments or needing more space for drag slicks, without giving up the structural support your chassis needs to perform.
