Drivetrain Mounts and Upgrades

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.

This package of OEM E82 E90 E92 diff mounts replaces the stock rubber diff bushings. On a tuned 335i you may have noticed more driveline shudder or problems hooking up during hard launches. What happens is the stock rubber bushings are under constant flex as engine torque is transmitted through the differential. Under normal driving with a stock car the bushings are rarely stressed. But factor in significant additional torque from a tuned N54/N55 and the stock rubber will quickly show its weaknesses. You may have even broken a diff bolt or two as the heavy differential shifts around. Even non-turbo E82 and E9X models may benefit from fresh bushings.

This is a set of stock rubber bushings, made by OEM supplier Lemforder. They are the same as the Genuine BMW E9X diff mount bushings, but without the more expensive branding. If you're turned off by potential side effects of urethane or Delrin then the OEM diff mounts are your best option. The OEM mounts fit and perform just like the originals so there is no second guessing their quality. If you're looking for an upgrade we offer E9X solid Delrin and aluminum diff mounts that work well, even in street applications.

E9X Diff Mount Set includes:

• 33176760287 x 2, front differential mount
• 33176770866 x 1, rear differential mount
• (new hardware is optional and can be ordered separately below)

The middle ground is Polyurethane. Polyurethane is much stiffer than rubber, but these still let a large amount of movement in comparison to solid mounts. These are great for sporty, aggressive street driving, but for the track are not ideal.

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.

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.
