As your E30 ages, the rear differential bushing can crack, dry rot, and split. It's time for an upgrade. The ECS Tuning Heavy Duty Differential Bushing is crafted with performance in mind. Instead of using polyurethane, which is known for increasing NVH, the enthusiasts at ECS chose HD 70D rubber. This material offers a close-to-factory feel without the excess deflection of softer bushings, ensuring a pleasurable driving experience free from differential whine and excess movement.

Features & Benefits:

Eliminates Weak OEM Mount: The aging E30 chassis deserves an upgrade. Replace your old, cracked, and worn factory bushing with this HD alternative for improved performance. Perfect for Street or Track: Constructed from HD rubber instead of polyurethane or Delrin, this bushing provides comfort for daily driving while remaining effective in performance applications. Added Responsiveness: The 70D HD rubber compound is stiffer than the stock material, reducing drivetrain movement and effectively locking down your rear differential. Easy Installation: Precision-manufactured to the exact specifications of your OEM differential bushing, the ECS heavy-duty replacement installs just like the factory component. Whether you are replacing an aging factory bushing, removing excess driveline movement, or balancing performance and comfort, ECS Tuning has you covered with their Heavy Duty Rear Differential Bushing.

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.

The subframe serves as the mounting point for your rear suspension system. It connects to the body using bushings designed to absorb vibrations at all attachment points. These bushings play a crucial role in dampening vibrations that could otherwise be transmitted to the cabin, ensuring the subframe remains stable. Additionally, they provide a secure mounting surface, maintaining tightness throughout the assembly. If you notice excessive vibration inside your cabin or hear clunking or knocking sounds when driving over bumps, the issue may be related to your subframe bushings.
