These mounts are a performance upgrade over the factory A4/A5 and S4/S5 mounts, but made with a softer 50 durometer rubber damping medium to limit unwanted noise and vibration transfer into the cabin on 2.0 TFSI equipped vehicles.

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 void-free and fluid-free, eliminating the slop associated with the factory mounts.

Track Density:

034Motorsport Track Density Engine Mounts are manufactured from 50 durometer rubber, which is a noiticeable upgrade from the 45 durometer rubber used in stock B8/B8.5 Audi S4 mounts. Since the mounts are also void-free and solid-filled, the resulting mount is substantially stiffer than stock, without introducing any additional noise, vibration, or harshness into the cabin. The mount bodies are made from high quality cast aluminum using OEM production techniques.

The result is greatly reduced drivetrain slop, crisper shifting, and minimal wheel hop, without any noticeable increase in noise, vibration, or harshness (NVH) inside of the cabin. The solid rubber, void-free and fluid-free design eliminates the possibility of leakage and collapse, which is a very common issue with factory mounts. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts. They were tested thoroughly in-house at 034Motorsport, JH Motorsports, and by fellow Audi enthusiasts before release.

Factory Active Mount Emulators:

034Motorsport Track Density Engine Mounts utilize emulators to replicate the electronics of the factory engine mounts for plug-and-play installation. This ensures MIL-free operation for cars equipped with active engine 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 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.
