ECS Tuning's Polyurethane Transmission Mounts are designed to address the vital role of transmission mounts in your vehicle's suspension. The factory mounts are notorious for failures that can result in over-revving, mis-shifts, and in extreme cases, potential chassis damage. Our polyurethane mounts provide a robust solution, engineered for both street and track applications, guaranteeing enhanced performance while eliminating concerns about torn mounts.
Polyurethane stands out with its exceptional toughness, durability, and impressive wear resistance compared to rubber. It also exhibits resistance to water, oil, and grease while retaining its original shape even when subjected to significant compression. By reducing deflection, polyurethane facilitates effective power transfer. While there may be a slight increase in NVH (Noise, Vibration, Harshness), the benefits far outweigh this minor compromise in ride comfort. With a polyurethane durometer of 70A, our street mounts are versatile, offering both daily driving comfort and track durability. For more track-oriented enthusiasts, we provide stiffer mounts with an 80A durometer rating.
For a hassle-free installation, we supply a comprehensive DIY guide. ECS Tuning ensures that you are fully supported from start to finish.

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.

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).
