034Motorsport Street Sport Engine/Transmission Mount Pair Audi 8S TTRS and 8V.5 RS3
034Motorsport Track Sport Engine Mounts for Audi 8S TTRS and 8V.5 RS3 models are the new standard in ultra-high performance. These mounts are designed with extreme performance in mind, manufactured from billet aluminium and high-durometer rubber, making them virtually indestructible, while maintaining better ride characteristics than polyurethane alternatives. These mounts have a lifetime guarantee regardless of the power level applied and the type of track racing they are used for.
Engineare void-free and fluid-free, eliminating the slop associated with the factory engine/transmission mounts, and are designed to be completely rebuildable with replaceable Density Line rubber bushings. These heavy-duty mounts will result in a moderate increase in noise, vibration, and harshness (NVH) transfer into the cabin, as they are designed to drastically reduce engine movement compared to the factory parts, but will introduce less NVH than our TrackSport mounts due to the lower-durometer rubber used. Additional NVH is most noticeable at idle, but once the vehicle is moving, NVH is slightly higher than stock.
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 the 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.
BUYER’S GUIDE
The following guide is designed to help customers choose which mount best meets their specific needs.
| StreetSport | TrackSport | |
