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 MkV/MkVI and 8J/8P 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 sped bumps, or travelling 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 centre 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.
