Description
The BMS Differential Support Bracket Brace for G-Chassis BMW and Toyota Supra is a purpose-engineered drivetrain reinforcement designed to correct a known weakness in the factory rear differential mounting system. Under hard launches, aggressive shifting, and increased torque loads, the OEM differential mount allows excessive movement—leading to wheel hop, inconsistent traction, accelerated bearing wear, and an unstable rear-end feel.
At elevated power levels, this unwanted differential movement does more than hurt performance—it compromises long-term drivetrain reliability.
The BMS Solution
The BMS Differential Brace rigidly ties the rear differential to the subframe, eliminating deflection and keeping the drivetrain planted under load. The result is improved traction, cleaner launches, and a more connected, confidence-inspiring rear chassis.
This is not a generic or universal brace. Every contour of the BMS Differential Support Bracket was designed using high-resolution 3D laser scanning of the factory subframe and differential housing, ensuring a precise, stress-free OEM-level fit. The one-piece heavy-gauge steel construction eliminates flex points common in multi-piece designs, while oversized M12 mounting hardware delivers significantly greater clamping force than factory or typical aftermarket solutions.
The finished product integrates seamlessly with the vehicle, delivering factory-like fitment with substantially improved strength and rigidity—engineered to withstand real power and real driving.
