The Street Density Transmission Mounts for the BMW E9X M3 are designed to replace your M3’s worn factory transmission mounts with performance-engineered Street Density Mounts to restore responsiveness and shifting feel beyond factory levels. 034Motorsport's Street Density Mounts are the new standard in comfort and performance. These mounts are redesigned with performance in mind and manufactured from high-durometer rubber for increased performance and durability without sacrificing comfort. Street Density Line Mounts are optimized internally-void-free and fluid-free, eliminating the slop associated with the factory mounts, resulting in improved shifting feel and driving dynamics.
NVH Levels: Low
NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. The 034Motorsport Street Density Transmission Mounts transfer low amounts of NVH to the cabin based on user feedback. This can also vary based on the transmission type your BMW is equipped with. NVH is subjective, so some users may find NVH to be increased or decreased from our rating.

Product Description:
034Motorsport's Street Density Mounts are the new standard in comfort and performance. These mounts are redesigned with performance in mind and manufactured from high-durometer rubber for increased performance and durability without sacrificing comfort. Street Density Line Mounts are void-free and fluid-free, eliminating the slop associated with the factory mounts.
034Motorsport Street Density Engine Mounts are manufactured from 70-durometer rubber, which is a significant upgrade from the 60-durometer rubber used in stock BMW E9X M3 transmission mounts. The tail shaft of the transmission compresses the mounts, as well as puts tension on them by pulling up on the mounts, meaning that the mount materials should be able to withstand both forces. In addition to these two forces, there are also shear twisting forces within the transmission mount assembly. Given that Polyurethane cannot reliably withstand these forces, it is not a long-term viable material to use for an upgrade in this location. Rubber is the ideal material for this transmission mount upgrade, as it is able to deal with stress under tension, compression, and shear.
The result is greatly reduced drivetrain slop and crisper shifting with a small 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.
