Overview

The 034Motorsport Density Line Transmission Mounts are performance-engineered components designed to replace the factory mounts on the BMW E9X M3. These mounts are manufactured from high-durometer rubber, featuring a void-free and fluid-free construction to eliminate slop and improve shifting feel and driving dynamics.

Available in two options, the 60 Durometer Street Density offers OE-like NVH with reduced drivetrain slop and crisper shifting. The 70 Durometer Track Density provides further drivetrain control and a more direct shift feel, though with moderate vibrations and transmission whine audible in the cabin. Both options are a complete drop-in replacement pair for the stock transmission mounts.
Show original supplier description
The 034Motorsport Density Line Transmission Mounts are designed as a performance upgrade for the BMW E9X M3, replacing worn factory transmission mounts. They are constructed from high-durometer rubber, offering increased performance and durability while minimizing comfort sacrifice. The void-free and fluid-free design of these mounts effectively eliminates drivetrain slop, leading to improved shifting precision and overall driving dynamics. 034Motorsport offers these transmission mounts in two distinct durometer options: 60 Durometer Street Density and 70 Durometer Track Density. The Street Density option provides none to low NVH (Noise, Vibration, Harshness) transfer to the cabin, making it ideal for daily and spirited driving. The Track Density option offers a more direct feel with further reduced slop, suitable for aggressive street and track use, though it may introduce moderate vibrations and transmission whine. Both mount options are manufactured using void-free and fluid-free rubber construction, a significant improvement over the stock fluid-filled rubber mounts. This material choice is ideal as rubber can withstand the stress of tension, compression, and shear forces. The solid-rubber, void-free design also eliminates the risk of collapse, a common issue with OEM mounts. These are complete, re-engineered performance solutions, not simple inserts for existing mounts. Each pair is sold as a complete drop-in replacement for the factory transmission mounts.
