Street Density Transmission Mount BMW E9X M3

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.
