BMW Drivetrain Parts

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

For G-Chassis BMW & A90/A91 Toyota Supra High torque loads, hard launches, and aggressive driving expose the factory differential mounting’s built-in compliance. Under power, the differential can shift excessively, resulting in wheel hop, inconsistent traction, and increased stress on drivetrain components—issues that become more pronounced on tuned or track-driven cars. The BMS Differential Support Bracket Brace corrects this weakness by reinforcing the differential mounting point and securely tying it to the subframe. By controlling unwanted movement, the brace improves rear-end stability and ensures power is transferred to the ground more efficiently. Why Upgrade? OEM differential mounts favor NVH reduction over control. As torque output increases, that compliance translates into drivetrain shock and lost traction. This brace stiffens the system where it matters most, reducing flex and improving load management under acceleration. Performance Benefits Improved launch consistency Significant reduction in wheel hop Increased rear-end stability under load More precise and predictable power delivery Engineered for Demanding Use Designed around factory mounting points, the BMS Differential Support Bracket delivers precise OE-level fitment with increased structural rigidity. Its robust construction resists deflection under high torque, while upgraded hardware provides greater clamping force for long-term reliability. Fully bolt-on for straightforward installation on both stock and modified vehicles. Key Features Reinforces rear differential mounting Limits differential movement under load Enhances traction and drivetrain response Heavy-duty construction for high-performance applications Bolt-on installation using factory locations Compatible with G-chassis BMW and A90/A91 Supra A focused drivetrain upgrade for drivers who demand consistency, control, and durability at higher performance levels.
