BMR F Chassis Billet Differential Brace for BMW F3X

Black Market Race F22, F23, F30, F32, F33 Billet Diff Brace Kit

My apologies for the wait, F Chassis Braces are here!

Inspired and designed with the same characteristics as our popular brace for the G chassis BMW's, this diff brace provides maximum support and rigidity to the differential by utilizing four of the OEM mounting points to our billet bracket, tied to the sub frame using a 1/4" steel bracket!

The Black Market Race F Chassis Differential Brace is a supplemental brace that connects the rear differential cover directly to the subframe, significantly reducing flex and stabilizing the drivetrain under load. This added reinforcement improves traction, throttle response, and reduces wheel hop—without replacing the factory mounts.

• Adds a solid rear mount to reduce differential movement under load
• Improves traction, throttle response, and drivetrain stability
• Includes all stainless steel hardware and drill bit needed for install.
• Requires drilling two holes in the subframe
• Bolt-on installation with no removal of factory mounts
