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. 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.
