Product Description:
034Motorsport's 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. Density Line Mounts are void-free and fluid-free, eliminating the slop associated with the factory mounts.
034Motorsport Density Line Transmission Mounts are manufactured from a 60 Durometer or 70 Durometer, void-free and fluid-free construction, which is a significant upgrade from the fluid-filled rubber used in stock BMW E9X M3 transmission mounts. The tail shaft of the transmission compresses and pulls up on the mounts, meaning the mount materials should be able to withstand both forces. In addition to these two forces, there are shear-twisting forces within the transmission mount assembly. Given that Polyurethane cannot withstand these forces reliably, it is not a long-term viable material for an upgrade in this location. Rubber is the ideal material for this transmission mount upgrade, as it can withstand stress under tension, compression, and shear.
The result is greatly reduced drivetrain slop and crisper shifting, with little to no increase in noise, vibration, or harshness (NVH) inside the cabin. The solid-rubber, void-free design eliminates the risk of collapse, a common issue with factory mounts. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.
