Street Density:

The Street Density Strut Mount is available in 60 or 70 durometer rubber options and is fully vulcanized to the center cups, significantly increasing its lifespan and performance over factory mounts.

The steel strut mount bodies have also been redesigned to cope with the added stresses of spirited driving.

The result is a significant reduction in the strut mount's deflection. These mounts will also eliminate the annoying "squeaking" sound often caused by the stock strut mounts when paired with coilover suspensions. Street Density Strut Mounts will only cause a minimal increase in noise, vibration, and harshness (NVH) inside the cabin. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.

Which mount should I choose?

Our 60-durometer Street-Density Strut Mounts are a great option if you’re looking for an OEM+-oriented upgrade. They offer better performance than factory mounts without compromising comfort. These mounts produce slightly more NVH than factory mounts. 70 Durometer Street Density Strut Mounts are our performance-oriented mounts. They offer the best performance while introducing some NVH into the cabin. This stiffer rubber durometer further reduces deflection in the front suspension, resulting in more precise handling and steering under heavy load.

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 and bushings.

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.

Technical Insight:

While the redesigned Volkswagen/Audi strut mount for the MkVII and 8V/8S chassis was a great improvement over the previous generations of strut mounts, they leave much to be desired when paired with performance dampers or coilover suspensions.

Many owners experience a "squeaking" sound coming from the front strut mounts after installing performance dampers or coilover suspensions. The noise becomes noticeable when pulling out of driveways, going over speed bumps, or traveling at low speed over uneven surfaces.

This "squeaking" is caused by the low durometer rubber used in the factory strut mounts, which causes the steel center cup to move inside of the rubber mount. Our Track Density Strut Mount Pair was designed to eliminate this annoying issue, and improve the performance of the vehicle's suspension.
