Drivetrain Mounts and Upgrades for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

Please ensure your correct model is selected

From the factory, engine and transmission mounts are rubber and thus a wear component. Worn out engine or transmission mounts create sloppiness and a disconnect between the driver and your BMW's powerplant. If your vehicle is purpose built for the track, we recommend solid engine and transmission mounts. These have zero deflection, but come at the expense of added NVH (noise, vibration, and harshness). Poly engine and transmission mounts offer a good balance between OEM rubber and solid mounts for those with mixed purpose vehicles, offering great performance and connection with little sacrifice in terms of NVH.

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.

Enhance your driving experience with ECS Tuning's Performance Polyurethane Differential Bushings. These meticulously engineered bushings offer a direct connection between your right foot, the engine, and the chassis, making them an essential upgrade.

  • Say goodbye to the softness of factory rubber differential bushings that absorb vibrations and reduce performance.
  • ECS Tuning's polyurethane bushings eliminate the deflection found in factory rubber bushings, resulting in improved power transfer from the differential to the wheels.
  • Experience enhanced throttle control, whether you're navigating a challenging canyon road, drag racing, or simply commuting.

Unlike delrin or solid differential mounts, these bushings deliver improved performance without introducing harshness or excessive vibration.

Crafted from durable 88A durometer polyurethane and enhanced with a black anodized 6061-T6 aluminum sleeve.

Resistant to chemicals, ozone degradation, road salt, and general wear and tear, ensuring a longer service life.

These rubber bushings from Meyle are a direct replacement for the stock differential bushings in the E46 3-series, E83 X3 SAV, and Z4 Roadster. If your original bushings are worn (likely around 100,000 miles) these are a great replacement upgrade. The front bushings are the stock OEM type rubber bushings. The rear bushing is a Meyle HD upgrade over stock - about 15% stiffer than the originals. This means the bushing will not flex and twist as much. This puts more power to the wheels since power is no longer used up for 'torquing' the bushing. These are not race bushings; the rubber material is perfectly suitable for street use.

The non-M E46/E83/Z4 models use three differential mounts - two front bushings in the subframe and one rear mount in the diff cover. This set of bushings covers all three. You can opt to include new mounting hardware in the Options list below.

This item fits the following BMWs:
1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi

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.

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.

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).
