Transmission Mount, Street Density Line, BMW
We're proud to announce the availability of our new Density Line Transmission Mounts for BMWs! 034Motorsport's Density Line Mounts are the new standard in comfort and performance. Our mounts are redesigned with performance in mind, and manufactured from high-durometer rubber for increased performance and durability, without sacrificing comfort. Density Line Mounts are void-free and fluid-free, eliminating the slop associated with the factory mounts, resulting in improved shifting feel and driving dynamics.
NVH Levels: None
NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. 034Motorsport Street Density Transmission Mounts will transfer zero amounts of NVH to the cabin based on user feedback. NVH is subjective so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please email techsupport@034motorsport.com for further assistance.

034Motorsport's Density Line Mounts are the new standard in comfort and performance.

Density Line Mounts are void-free and fluid-free, eliminating the slop associated with the factory mounts.
Street Density:
034Motorsport Street Density Engine Mounts are manufactured from 60 durometer rubber, which is a significant upgrade from the 45 durometer rubber used in stock BMW transmission mounts.
The result is greatly reduced drivetrain slop and crisper shifting, without any noticeable increase in noise, vibration, or harshness (NVH) inside of the cabin. The solid rubber, void-free design eliminates the possibility of collapse, which is a very common issue with factory mounts. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.
Features:
- Manufactured from 60 Durometer (Street Density) Rubber with Void-Free Construction
- Reduced Drivetrain Slop
- Decreased Transmission Movement Under Load
- More Direct Power Transfer
- Improved Shifting Feel
- Complete Drop-In Replacement of Factory Engine Mount
- Sold Individually (One Vehicle Requires 2 Mounts!)

High-Durometer Rubber vs. Polyurethane:
Density Line Mounts are manufactured from high-durometer rubber instead of polyurethane for a number of reasons. While vulcanized rubber mounts are more expensive to prototype due to increased complexity of manufacturing and high initial tooling costs, rubber is inherently better than polyurethane as a damping medium for mounts and bushings.
Rubber is able to deal with stress under both tension and compression, while polyurethane mounts rely on the damping medium to be effective only under compression. Rubber is also excellent in shear, where polyurethane is ineffective, making it ideal for applications that apply a shear force to the bushing during articulation.
Rubber does not pack and wear like polyurethane does, which ultimately results in a long-lasting part with consistent performance and comfort.
