High-Durometer Rubber vs. Polyurethane:
 
Density Line Mounts are manufactured from high-durometer rubber instead of polyurethane for a number of reasons. While vulcanized rubber mounts are more expensive to prototype due to increased complexity of manufacturing and high initial tooling costs, rubber is inherently better than polyurethane as a damping medium for mounts.
Rubber is able to deal with stress under both tension and compression, while polyurethane mounts rely on the damping medium to be effective only under compression. Rubber is also excellent in shear, where polyurethane is ineffective, making it ideal for suspension bushings that apply a shear force to the bushing during articulation.
Rubber does not pack and wear like polyurethane does, which ultimately results in a long-lasting part with consistent performance and comfort.

034Motorsport Street Density Snub Mounts are manufactured from 65-durometer rubber, which is approximately 30% stiffer than the failure-prone factory mounts.
The steel bases have also been redesigned to cope with the added stresses of spirited driving and increased torque.

The result is a significant reduction in engine movement, solid shifting, and increased mount longevity. Street Density Snub Mounts may cause a slight noticeable increase in noise, vibration, and harshness (NVH) inside of the cabin.
These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.
