We're proud to announce the availability of our new Density Line Engine Mounts for the B8 Audi S5/RS5 4.2L FSI V8!

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.

Street Density:

034Motorsport Street Density Engine Mounts are manufactured from 65 durometer rubber, which is a significant upgrade from the 45 durometer rubber used in stock B8 Audi S5/RS5 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 Street 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. 

Features:

  • Manufactured from 65 Durometer (Street Density) Rubber with Void-Free Construction
  • Built-In Emulator with Plug-In Connector for Vehicles Equipped with Factory Active Mounts
  • Reduced Drivetrain Slop
  • Decreased Engine Movement Under Load
  • More Direct Power Transfer
  • Improved Shifting Feel
  • Complete Drop-In Replacement of Factory Engine Mounts
  • Sold in Pairs!
Fitment:
  • 2008 - 2011 Audi S5 (B8)
    • 4.2L FSI
  • 2012 - 2017 Audi RS5 (B8) 
    • 4.2L FSI
Replaces:
  • 8R0198381F /  8R0 198 381F

Installation Instructions:

  • Please Note: We highly recommend having these mounts installed by an experienced mechanic. The installation process is the same as the factory mount remove and replace procedure. Our installation guide is meant to supplement the factory procedure.
    • Only 1 mount requires the included spacers, and should be installed on the passenger side of the car. Both mounts may come with spacers installed, and if so, remove the aluminum spacers from one mount and use on the driver's side of the car.

Warranty:

  • 1 Year Limited Replacement Warranty (If you encounter any issues with our products outside of the warranty period, we will work with you to provide a resolution.)

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.

Simple valet tray that finally keeps my pockets from exploding on the nightstand
Color: Black, Size: Sectional, Color: Black, Size: Sectional
This valet tray is one of those small things that makes daily life a little easier. I like the sectional layout because it gives everything its own spot instead of just tossing a pile of keys and a wallet together. The phone slot is angled so you can actually see the screen when it is sitting there, which is a nice touch. The inside lining feels soft so it helps with scratches and it also cuts down that loud clanking sound when you drop keys in it. The non slip base matters more than I expected since it keeps the tray from sliding when you grab stuff in a hurry. Size wise it fits the normal everyday carry stuff without being huge. If you want your entryway or nightstand to look less messy, this does the job.

Thoughtfully Designed Tray
Color: Black, Size: Sectional
Such a simple item, but Spigen was very thoughtful in some of the subtle design feature. This is not just a box with dividers. Each compartment is actually sloped, which makes grabbing an item ergonomic, allowing you to just pull something to the edge instead of the often awkward battle against the walled edges of a traditional design. Yes, it's just a tray, but I appreciate its thoughtful design.

Keep your essentials all in one place
Color: Black, Size: Sectional, Color: Black, Size: Sectional
Picked this up to declutter my nightstand and it’s honestly been a solid little upgrade. The layout is super practical, there are 4 compartments and they’re actually sized well, not just random sections. I can fit my keys, wallet, watch, and random small stuff without everything piling on top of each other. The phone slot is a nice touch too. It’s angled just enough that I can glance at notifications or watch something while it charges. Didn’t even miss having a cable hole like I thought I would. Build quality feels better than expected. It’s lightweight but still sturdy, and the outside has a clean, modern look. The inside lining is soft, so when you toss your keys or watch in, it doesn’t make that annoying clatter or scratch things up. Also appreciate the non-slip bottom, it actually stays put when you grab stuff instead of sliding all over the place. Overall, simple but well thought out. If you’re tired of your everyday carry stuff being scattered everywhere, this does the job nicely. For the price point, this is a great value 👌 👏
