034Motorsport's Motorsport StreetSport 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 aluminum and high-durometer rubber, making them virtually indestructible, while maintaining better ride characteristics than polyurethane alternatives. These mounts have a lifetime guarantee regardless of power level applied and type of track racing they are used for.

Motorsport StreetSport Mounts are 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 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.

Hard to assemble
Color: Grey
This is extremely hard to put together, but once its together it is pretty good. You will need to secure it to something. It falls over.

Do not buy this protection plan!
Warning! The details of this Warranty are misleading and make you feel like they will pretty much replace anything. I am trying to have stained discolored cushions replaced on lounge chairs, less than six months old. Talking to a customer service representative is out of the question. They ask a few multiple-choice questions and base your claim on that. My claim was denied and that is the end of it. I have spent $80.99 on two different asurion protection plans need and now I feel like I have wasted $162.00. I'm not happy and will never buy this protection plan again. Now I have to find and purchase new cushions for replacement.
