034Motorsport Street Density Snub Mounts are designed as a direct, high-performance replacement for factory mounts in the B7 Audi RS4 and C5 Audi RS6. Unlike polyurethane alternatives, these mounts are manufactured from 65-durometer vulcanized rubber, offering superior damping, durability, and consistent performance under spirited driving conditions.
Why Rubber Outperforms Polyurethane:
-
Rubber handles both tension and compression, whereas polyurethane is effective mainly under compression.
-
Excellent in shear, making it ideal for suspension and engine mounts where lateral forces are present.
-
Resists packing and wear over time, ensuring long-lasting comfort and consistent performance.
Street Density Snub Mount Benefits:
-
Approximately 30% stiffer than factory mounts for reduced engine movement.
-
Redesigned steel bases to withstand increased torque and spirited driving.
-
Improved throttle response and shift feel.
-
Increases mount longevity compared to factory units.
-
Slightly increased NVH is noticeable but acceptable for street performance.
-
Costs ~75% less than factory replacements.
