We're proud to announce the availability of Density Line Strut Mounts for early small chassis Audi models, including the UrQuattro, 4000, Coupe GT, B3/B4 80/90/Coupe Quattro, S2, RS2 and others!

034Motorsport's Density Line Mounts are the new standard in comfort and performance. Our 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 engineered to be stiffer than stock and eliminate the slop associated with the factory mounts.

Street Density

The Street Density Strut Mount is manufactured from 60 durometer rubber, which is approximately 10% stiffer than stock, and features a reinforced design that makes it effectively 25% stiffer than stock. The rubber is fully vulcanized to the center cups to ensure improved performance and lifespan.

The result is a significant reduction in deflection of the strut mount. Street Density Strut Mounts will not cause any 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.

Track Density

The Track Density Strut Mount is manufactured from 80 durometer rubber, which is approximately 90% stiffer than stock, and features a reinforced design that makes it over twice as stiff. The rubber is fully vulcanized to the center cups to ensure improved performance and lifespan.

The result is a significant reduction in deflection of the strut mount. Track Density Strut Mounts will cause a minimal 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.

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.

Please Note: One vehicle requires 2 mounts per axle or 4 mounts total. New strut mount bushings are available as an option here.
