034 Motorsport Motor Mount, Street Density Audi S4/S5/SQ5 B9 3.0 TFSI, RS4/RS5 2.9 TFSI
 
034Motorsport Street Density Motor Mounts for the B9/B9.5 Audi S4/S5/SQ5 3.0 TFSI & RS4/RS5 2.9 TFSI are a performance upgrade over the factory mounts, and are a Track Density Upgrade for the B9/B9.5 Audi A4/A5 2.0 TFSI. Street Density Motor Mounts are manufactured with 60 durometer rubber to limit unwanted noise and vibration transfer into the cabin. Street Density Motor Mounts are optimized void-free and fluid-free, eliminating the slop and excess movement associated with the factory mounts, resulting in improved shifting feel and driving dynamics while greatly improving long term durability and longevity. Note: This mount has two different applications based on engine size (Street Density for 6-Cyl 3.0 TFSI and Track Density for 4-Cyl 2.0 TFSI). Please see the Fitment Guide tab below for application information.
 
034Motorsport Street Density Motor Mounts are the new standard in comfort and performance. These mounts are redesigned with performance in mind, and manufactured from high-durometer rubber for increased performance and durability, without sacrificing comfort. Street Density Motor Mounts are optimized void-free and fluid-free, eliminating the slop and the possibility of leakage and collapse associated with the factory mounts. The mount bodies are made from high-quality cast aluminum using OEM production techniques and employ emulators to replicate the electronics of the factory motor mounts for plug-and-play installation. This ensures MIL-free operation for cars equipped with active motor mounts.

Street Density Motor 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 the 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 applications 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.

The 034Motorsport Street Density Motor Mounts are designed to be an OEM+ replacement for B9/B9.5 Audi S4/S5/SQ5 3.0 TFSI and B9/B9.5 Audi RS4/RS5 2.9 TFSI. These mounts offer improved performance and decreased deflection over the stock S/RS Audi motor mounts, without the failure-prone liquid-filled design.
