Drivetrain Mounts and Upgrades for BMW 3 Series E46 (1999-2005)

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.

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.

When working on the rear subframe, replacement of any rubber bushings and mounts should be performed. This is the front differential mount bushing and it takes the majority of the torquing motion of the diff when under load. The constant twisting will cause this bushing to wear out pretty fast. This is the Original BMW rubber part.

Applications:
2001-2006 E46 M3, M3 CSL coupe and convertible
2007-up Z4 M Roadster, M Coupe

This is the stock transmission mount for the E46 M3 (6 speed manual). As the rubber mounts wear there is more flex and twist as the engine delivers torque. This can also throw off the alignment of the shift linkage and lead to difficult shifting. If left alone the sloppiness in the driveline could lead to a mis-shift and an expensive engine rebuild. This is the Original BMW M3 transmission mount for the best quality.

Thanks to the higher engine output in the E46 M3, this mount can also be used on the non-M E36 and E46 models as an upgrade. A good mild / street upgrade if your transmission mounts are worn, but still want to maintain good ride comfort.

Sold individually, 2 needed per car.

This transmission mount fits the following BMWs:
1992-1999 E36 3 Series including 325i, 325is, 328i, 328is & 323is (5 speed manual)
1995-1999 E36 M3 (manual transmission)
1999-2005 E46 3 Series including 323i, 323Ci, 328i, 328Ci, 325i, 325Ci, 330i, 330Ci (manual transmission)

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.

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. 

This part fits the following BMWs:
2001 - 2006 E46 M3

If your transfer case bushing is old, hardened, or cracked, it can lead to excess noise and vibration. Worn out mounts can also cause damage to other driveline mounts over time if not addressed. Replace your transfer case mount with this new mount to eliminate noise and vibration and prevent further wear and tear.

Powerflex's new transfer case bushing insert is made from polyurethane and is designed to reinforce your OE rubber transfer case bushing. This helps to stiffen the bushing and limits excessive movement of the transfer case. This Black Series bushing is rated at 95A durometer, which is significantly stiffer than your OE bushing's rubber. This is perfect for someone who tracks their BMW regularly and is looking for the best performance possible without going for a solid mount solution. As this bushing is 95A durometer, a significant amount of extra NVH should be expected.

With bad transmission mounts, excessive vibration and noise is transferred to the cabin. The rubber in the mounts wear out over time and cause too much movement in the drivetrain. Replace them when wear is detected to keep everything tight.
