Everyone knows that heat is the enemy of your automatic transmission. And everyone knows that higher power levels generate more transmission fluid heat. Now you can extend the life of your automatic transmission by installing the new Burger Motorsports High Capacity Trans Cooler kit. This unique plug-and-play kit replaces your factory coolant to trans fluid heat exchanger with a high-capacity fender-mounted air-to-trans fluid radiator. Includes all mounting hardware, lines, and coolant caps required for installation. Installs inside the driverside fender providing ample airflow over the large cooling core via existing openings. The result is dramatically reduced transmission temperature and extended transmission life. This kit is strongly suggested for any BMW E chassis automatic running larger than factory turbos. The thermostat maintains the oil exiting the transmission at the rated minimum temperature in most conditions. Without a thermostat, the transmission fluid coolers are likely to over-cool the fluid, delaying transmission warm-up and performing the critical function of bypassing the cooler until the oil has reached its minimum operating temperature. FEATURES AND BENEFITS Dissipates excess transmission fluid heat Reduces transmission fluid temperature Increases transmission life when racing Increases transmission oil capacity Fitment: 2008-2013 E81 E82 E87 Coupe and Hatchback 135i 2008-2013 E88 Convertible 135i Compatible with both RHD and LHD vehicles.

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.
