Frequently Asked Questions
The Problem
Hard launches, aggressive shifts, and high torque loads all expose a weakness in the factory rear differential mounting. Excessive differential movement leads to wheel hop, inconsistent launches, added stress on differential bearings, and a vague or unstable feeling from the rear of the car. Over time, that movement does more than hurt performance. It accelerates wear and compromises drivetrain reliability. Especially at higher power levels.
The Solution - The BMS Differential Brace
The BMS Diff Brace was engineered to eliminate unwanted differential movement by rigidly tying the rear differential to the subframe. The result is a planted, confidence-inspiring rear chassis that puts power down cleanly and consistently.
This is not a generic brace. Every contour of the BMS Differential Brace was designed using high-resolution 3D laser scanning of the factory subframe and differential housing. This ensures a perfect, stress-free fit with zero guesswork. The one-piece heavy-gauge steel construction removes the flex points found in multi-piece designs, while oversized M12 hardware provides clamping force far beyond OEM and typical aftermarket solutions.
The end result is a component that feels like it belongs on the car from the factory, only stronger, tighter, and engineered for performance.
What You Will Feel
• Sharper, more controlled launches
• Dramatically reduced wheel hop
• A tighter, more stable rear chassis under acceleration
• Reduced load and shock on differential bearings
Engineering Highlights
• Designed using precision 3D laser scanning for an exact OEM-level fit
