BMS BMW E82 E88 E90 E93 Rear Differential Support Bracket Brace
Transform traction, stability and launch performance on your BMW 1 Series and 3 Series with the Burger Motorsports rear differential support bracket brace. This BMS diff brace ties the rear differential directly to the subframe for a tighter, more connected rear end, reducing wheel hop and axle tramp, improving straight-line launches and giving a more planted, confidence-inspiring chassis on fast road and track. Precision one-piece construction eliminates weld weak points found on multi-piece alternatives. Stealth design with no visible logos for an OEM-plus look.
Perfect for BMW E82 E88 E90 E93 platforms including 135i, 335i, 335xi xDrive, 335d and 335is, this heavy-duty rear differential brace is a proven upgrade that supports the driveline under load, reduces differential bearing stress and keeps power going to the tarmac. We’ve fitted these for customers and feedback has been consistently excellent for launch control, traction and overall rear-end stability.
