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.

Great diesel treatment for everyday use
Size: 128 fl. oz, 1 Pack
I use this Hot Shot’s Secret Everyday Diesel Treatment for my diesel truck, and it has been a great product to keep on hand. The 1-gallon size is a good value because it treats a lot of fuel and makes it easy to use regularly. I like that it is made for everyday diesel maintenance, not just occasional use, and it gives me extra confidence that I am taking better care of the fuel system. A very practical product for diesel owners who want something reliable for regular use.

Noticeable MPG boost for my F-250!
Size: 128 fl. oz, 1 Pack, Size: 128 fl. oz, 1 Pack
I’ve been using this Everyday Diesel Treatment in my F-250 for a while now, and the results are legit. The most impressive part is the improved fuel economy—I’m definitely getting more miles per gallon than before. ​The engine also sounds smoother and seems to have better throttle response. I love that this one-gallon jug treats so much fuel, making it a great value for the price. If you want to keep your fuel system clean and save some money at the pump, this is a must-have. Will definitely keep buying!

If you own a diesel engine, use this.
Size: 128 fl. oz, 1 Pack
For diesel owners looking to protect their fuel system, Hot Shot's Secret Everyday Diesel Treatment (EDT) is a heavy hitter in the world of additives. This 1-gallon jug is designed for the long haul, treating up to 1,280 gallons of fuel, which makes it incredibly cost-effective for daily drivers and fleet owners alike. The primary draw here is the 7-point cetane boost, which noticeably smooths out rough idles and improves cold starts. Beyond performance, it serves as a critical insurance policy against modern "dry" Ultra-Low Sulfur Diesel (ULSD) by adding essential lubricity to the fuel pump and injectors. It also features a demulsifier to help separate water from the fuel, preventing corrosion before it starts. While the 1-gallon bottle is bulky and requires a smaller dispenser for easy pouring at the pump, the peace of mind and improved MPG make it a staple for maintaining a healthy engine.
