Drivetrain Mount Kits for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Want to overhaul all of your old, tired drivetrain mounts? Our drivetrain mount packages generally include engine and transmission mounts, sometimes going back to subframe and diff bushings. When replacing engine and transmission mounts, it is important to keep both consistent in terms of a material. For example, if you are running poly engine mounts, you should run poly trans mounts. If you are running solid engine mounts, you should run solid engine mounts. Mixing the two can cause issues you don't want to deal with.

Made in the USA If allowed in the rules these solid aluminum engine and transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. We originally developed these mounts for E36 and E46 World Challenge racing but they also work perfect in BMW Modified and SCCA club racing and SpecE46 (SE46). These are machined from solid aluminum and have zero deflection. The engine torque will cause a rubber or urethane mount to flex or deflect. The stiffer the material the less movement there is and the more torque is passed through the driveline (instead of being wasted winding up the mount). At the transmission end the flex-free solid mounts will give smoother, crisper shifts since the transmission is no longer dancing on the pliable mount. This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of motor and transmission mounts you will ever need. We have designed these mounts so the engine is 5mm lower and the transmission is 1mm lower than the factory mounts. This helps lower the center of gravity for better balance and handling. We very strongly recommend using the transmission and engine mounts together as a complete kit. Mixing a rubber mount with a metal mount will cause undue stress on the mouting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used. This kit fits the E36, E46, Z3, and Z4 6 cylinder models listed below, including M3 models.

These are a no-compromise design for all-out racing use. Full solid aluminum mounts should not be used on street-driven cars. Because there is no material to absorb vibration these will be quite harsh for regular street use (track cars don't care about noise).

Subframe reinforcement kits are very strongly recommended to go along with these solid motor mounts to reduce the risk of damage to the subframe. The motor mount section of the subframe should be reinforced to prevent stress and failure of the subframe.

This item fits the following BMWs:

Stock mounts are made from soft rubber and are sometimes filled with fluid to give a car the most comfortable ride possible. The soft rubber and fluid helps to reduce the total amount of vibration, noise, and harshness (NVH) that is transferred into the cabin. The problem with this is driveline slop. The stock mounts allow a lot of excess movement and increases the amount of time it takes to transfer power to the wheels.

In order to address this issue, performance mounts can be substituted to reduce the amount of slop and transfer power to the wheel quicker. Two options for this are polyurethane mounts and solid mounts.

Solid mounts are great for an immediate transfer of power but allow for a ton of noise and vibration to be felt and heard in the cabin of the vehicle. This is great for the track where there aren't any issues with excess harshness, but as a daily driver, this can become an annoying pain in the neck.

The best middle ground is Polyurethane. Polyurethane is much stiffer than rubber and gives you the much stiffer feel you may be looking for. This allows for the increase in responsiveness, but isn't so extreme that it transfers all of the sound and vibrations into the cabin. This makes it much more comfortable for daily use while still reinforcing your driveline.

Features:

  • Aluminum and Polyurethane Construction
  • 80A Durometer Rating
  • New Hardware

Collapsing and worn engine mounts can mean big trouble for BMWs. The stock mounts are filled with fluid that can leak or evaporate over time. That leaves the mount unstable and too flexible to properly support the engine. The side effects of a worn engine mount are: shaking and vibrating engine, driveline twist from engine torque that can break or snap bushings, and broken motor mount arms and bolts. If you're tired of replacing engine mounts you'll be very pleased wtih these solid rubber versions. Not only are these more reliable than stock fluid-filled mounts, they are slightly stiffer than new stock mounts thanks to a solid rubber construction (no voids in the rubber) but designed for street use so they remain quiet and comfortable. The solid rubber has less deflection than a stock mount, so no wasted engine and transmission motion. Less wasted motion gives you more torque to the wheels (it's not spent twisting the engine) and better shifts.

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 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.

For the track, solid mounts are great. Solid mounts give you an immediate transfer of power, at the cost of increase NVH. This is great for the track where comfort is the least of your worries and power is all that is important.
