Please Note: Only available for purchase and shipment within the United States 

034Motorsport's Density Line Mounts are the new standard in comfort and performance from a rubber mount. Density Line mounts are designed with performance in mind, and manufactured from high-durometer rubber for increased performance and durability, without sacrificing comfort. Available exclusively at ECS Tuning, these are the ideal rubber mount for enthusiasts averse to the harshness found in some polyurethane mounts.

034Motorsport:
Long-time experts in popular rubber performance mounts for many Volkswagen/Audi vehicles, 034Motorsport has made its first foray into the BMW market through ECS Tuning. With over a decade of experience in developing track-proven and street-friendly performance upgrades, we saw 034 as an excellent partner from who to source high quality performance mounts we (and our customers) can trust.

Street Density:
The Street Density Transmission Mount is manufactured from solid 50 durometer rubber, which is stiffer than the stock hydraulic mount (45 durometer - with voids). The result is greatly reduced engine slop, delivering a better driving experience with better overall feel, all while without significant increase in noise, vibration, or harshness (NVH) inside of the cabin. These mounts are an engineered performance solution ideal for daily use.

Features and benefits:

  • Manufactured from 50 durometer rubber
  • Reduced engine slop with decreased engine movement under load
  • More direct power transfer with improved throttle response
  • Complete drop-in replacement of factory engine mounts

Ideal for use with upgraded transmission mounts.
