Find Parts That Fit Your Vehicle

Drivetrain Mounts and Upgrades

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.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

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.

These specific mounts are designed for those with clearance issues on extremely low E30s. They are 20mm taller than OEM mounts to add necessary clearance to ensure the oil pan sits above the stock subframe. Under hard braking the OEM rubber mounts allow the m20 to lean forward. Not only do these solid UHMW replacement mounts stiffen the engine and drivetrain, but they also raise the engine by 20mm, dramatically changing the responsiveness and raising the oil pan height of your E30. UHMW is an excellent general-purpose plastic with a unique combination of wear and corrosion resistance, low friction surface and impact strength. It is resistant to chemical attack and moisture absorption and retains key physical properties to -30 C. This kit includes Solid Transmission Mounts as well for fully solid powertrain mounting!

These mounts are designed for a BMW E30 M3. Revshift polyurethane motor mounts are made in the U.S.A. from high-grade polyurethane. Revshift mounts are the most durable and reliable mounts on the market. CNC machined billet aluminum flanged ends are embedded deep in the urethane which prevents the isolated ends from separating under extreme loads. Utilizing class 14.9 alloy steel removable screws these mounts will hold your engine in place for a lifetime. To further ensure the strength of these mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum end pieces. Revshift Performance Engineering is a high-performance parts manufacturer with a focus on quality, reliability, and performance. Utilizing high-precision machining technologies and their very own Polyurethane Manufacturing Department, every Revshift product is designed, manufactured, and tested in-house at their Detroit, Michigan facility.

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. 

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.

These aluminum mounts are a direct replacement for the stock rubber bushings and have been lightened to remove excess weight. Using aluminum instead of rubber eliminates the "wind up" inherent in rubber mounts, and this deflection slows suspension & drivetrain response. The tradeoff is an increase in NVH. Features: Stiffens chassis/Improves stability Less wear of other components Better durability Provides better control of chassis geometry Replaces OE: 33312284019, 33312283384 Recommended for racing use only Includes: 1 rear aluminum bushing 2 front aluminum bushings

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.
