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.

Enhance your car's performance with ECS Tuning's polyurethane transmission mounts, designed for both street and track applications. These mounts are engineered to withstand high torque and forced-induction scenarios, eliminating concerns about torn mounts and providing a more engaging driving experience. Although polyurethane may introduce some additional NVH (Noise, Vibration, Harshness), its exceptional durability, wear resistance, and resistance to water, oil, and grease make it the perfect choice for performance enthusiasts. ECS Tuning offers two durometer options to match your driving style, along with a comprehensive DIY installation guide, ensuring a complete solution for your transmission mount requirements.

Worn rubber differential mounts will lead to the differential twisting and shifting around in the rear subframe. Not only will this be noisy but it's bad for driver confidence and bad for the chassis as well. Even on fresh rubber bushings the differential has deflection and twist, especially if the car has been modified for more torque. Since the differential is centrally mounted in the rear subframe, with all suspension mounts interconnected, a differential with too much deflection will affect handling and could even damage the rear subframe.
These 88A urethane E46 M3 diff mounts are much stiffer than stock but still not as solid as our Turner aluminum/Delrin bushings. This set will resist twisting much better than the stock rubber mounts. Included is the front diff mount and two rear mounts in the cover.

This is the rear rubber-isolated differential mount. The diff mounts take the bulk of the twisting and binding as power is transmitted through the differential. We use a Meyle HD rubber bushing for the rear mount as it's stronger than the factory part. (33176751808). We also recommend replacing the front differential mount 33171093175MY at the same time.
Meyle is a German brand in business since 1958 and all of their products are TUV approved and meet or exceed ISO standards. Heavy Duty components are designed to provide significantly long lifespans than other aftermarket and stock OE components. Each part includes a 4 year warranty.
As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers.

A sloppy shifter is one of the common complaints of older BMWs. In addition to the shifter linkage the transmission mounts contribute to rough and clunky shifting. BMW transmission mounts are rubber and get softer over time. This allows the transmission to dance around which changes the geometry of the shift linkage and could make it harder to shift. These urethane transmission bushings are stiffer than the stock rubber mounts and won't let the transmission shift around as much. The round design also has more surface area than the stock mounts which helps spread the load. Because the urethane is stiffer, expect more vibration to make its way into the shift lever area. Engine motor mounts should also be considered as a cause for driveline vibration, transmission movement, and poor shifting. Consider replacing your motor mounts at the same time as your tranny mounts.
Price is for the pair of transmission mounts with hardware.

Drive line slop is often caused by faulty engine and transmission mounts. This can result in knocking noises under heavy acceleration, excessive vibration, and a less responsive feel in power. These OEM Febi and Lemforder mounts are perfect to eliminate these problems and provide long lasting reliability.

Your rear differential is indirectly connected to your right foot through the engine and driveline, and connected to the seat of your pants through the chassis. Soft factory rubber differential bushings absorb vibrations between chassis and differential, providing comfort and softness in both of these connections.
Enter ECS Tuning's In-House Engineered Performance Polyurethane Differential Bushings. By eliminating the deflection factory rubber bushings permit, the connection between your right foot (and your seat) to the wheels is improved. Removal of this slop allows for crisper power transfer from differential to wheels, which means better throttle control while carving a canyon road, drag racing, sliding the rear end out, or just driving to work. This is achieved without the harshness or vibration associated with delrin or solid differential mounts.
Featuring a tough 88A durometer polyurethane and Black anodized 6061-T6 aluminum Sleeve, our Performance Polyurethane Differential Bushings are more resistant to chemicals, ozone degradation, road salt, and general wear and tear than factory rubber bushings, resulting in a longer service life.

This kit includes Turner Motorsport solid aluminum differential race mounts pre installed in the differential cover for a quick install. These mounts where developed by Turner Motorsport for their Grand-Am Cup E46 M3 race cars, the advantages of solid aluminum mounts is increased suspension & drivetrain response, less drivetrain loss resulting in more wheel horsepower, and longevity - they effectively last forever. These CNC-machined mounts are a direct replacement for the stock rubber pieces, and have been lightened to remove excess weight.
