Street Density Strut Mount and Bearing Bundle Now Available from 034Motorsport

Product Description:

The 034Motorsport Street Density Strut Mount & Bearing Bundle includes a pair of 70 durometer Street Density Strut Mounts and replacement Strut Mount Bearings. This bundle contains the necessary pieces when replacing noisy and worn parts or when upgrading your front suspension.

The factory front strut bearings see a lot of load from the suspension, and can wear and become noisy over time. This bundle of mounts will also eliminate the annoying “squeaking” sound often caused by the stock strut mounts when paired with coilover suspensions. Street Density Strut Mounts will only cause a minimal increase in noise, vibration, and harshness (NVH) inside of the cabin. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.

The Street Density Strut Mount is manufactured from 70 durometer rubber, which is approximately 50% stiffer than stock. The rubber is also fully vulcanized to the center cups to increase the lifespan and performance of the mounts significantly.

The steel strut mount bodies have also been redesigned to cope with the added stresses of spirited driving.


  • Manufactured from 70 Durometer Rubber
  • Rubber Fully Vulcanized to Center Cups
  • Eliminates “Squeaking” Sound Caused by Factory Strut Mounts
  • Reduced Strut Mount Deflection
  • Maintain Proper Suspension Geometry Under Load
  • Improved Steering Feel & Handling
  • Complete Drop-In Replacement of Factory Strut Mounts
  • Priced as a Complete Set – Two of Each – at a Discounted Price Compared to Buying Individually

What’s Included:

  • 2x Street Density Strut Mount
  • 2x Factory Replacement Strut Bearing
  • 2x Hardened Steel Washer

OE Part Interchange:

  • 5Q0 412 331 D* – Strut Mount
  • 5Q0 412 249 E* – Strut Bearing
  • *And Any Subsequent Supersessions

034Motorsport Dynamic+ Tuning for B8 Audi A4, A5, & Q5 2.0T Now Available!

034Motorsport B8 Audi A4/A5 & Q5 2.0 TFSI (EA888 Gen 2) Performance Software Now Available & at 10% Off!

Check It Out Here!

Product Description:
The 034Motorsport Dynamic+ Stage 1 Tuning Software for Audi B8 A4/A5/Q5 (Not B8.5) equipped with the EA888 Gen 2 2.0T inline four engine is designed to transform the driving experience of your vehicle! Flashed directly through your vehicle’s OBD-II port, 034Motorsport’s proprietary calibrations for the ECU safely and effectively increase the power output of the turbocharged inline four in a refined manner. The result is a significant improvement in acceleration and throttle response, without any sacrifice in driveability or reliability.

034Motorsport Audi B8 A4/A5/Q5 EA888 Gen 2 2.0T Dynamic+ Performance Software was developed entirely in-house on 034Motorsport’s Development B8 A5. The calibrations were then refined on multiple enthusiast-owned beta tester cars around North America.

034Motorsport engineers develop special inhouse tools that allow us to access the firmware and maps inside the factory ECU, this level of engineering is required to prevent work-arounds and bandaids that many aftermarket companies resort to. 034Motorsport engineers and optimizes the ECU calibrations just like Audi engineers would, but accessing the source of how the ECU controls the engine and making changes at the base level.

This is the ONLY way 034Motorsport can ensure our calibrations meet our high standards for ultimate power with smooth drivability, perfect function, reliability and added functions and features even beyond what the factory programming can provide.

NOTE: The E85 calibration is not a flex-fuel style tune. The tune will work with E85 directly from the pump, both summer and winter blends (ethanol content can vary from E60-E85). This tune requires only E85 be pumped into the fuel tank. Gasoline blends and race fuel mixtures should not be used, and engine damage could occur if the incorrect fuel or octane is used. We strongly recommend an ethanol content gauge be used so that you can monitor the actual ethanol content at the pump you are using.

When switching fuels, it takes about 20-30 minutes of normal driving for the new tank of fuel to fully circulate through the system when filled at E. Please minimize load (don’t floor it!) until you have driven the car for at least 30 minutes. Ethanol content analyzers installed close to the fuel rail will also help you see when the ethanol has fully run through the system.

With increased power, comes increased heat. With increased heat, comes the need for additional management. For charge air temperature, 034Motorsport has implemented key safety features to keep your engine running optimally and safely in virtually any condition – just like the OEM calibration. Substantial effort was spent on balancing the trade off of charge temp for power, and improving the compressor efficiency so that it doesn’t generate too much charge temp.

Charge Air Temp: When the charge temp exceeds 80*C there is a reduction in power output. When the charge temp exceeds 85*C there is a more significant reduction in power output. This charge temp limitation is there to prevent knock events from excessive charge temps, which can severely damage a motor. With these safety measures in place, you can confidently drive your car, from the top of Pikes Peak to Death Valley, knowing the factory ECU has optimal performance and safety covered.


While E85 provides substantial increases in power, it requires about 30% more fuel than standard pump gasoline per ignition cycle. Utilizing a variety of fuel stratified injection strategies, 034Motorsport calibrators have further optimized the factory fueling system to be able to adequately support full E85 on factory hardware for Stage 1 and Stage 2 tunes.

034Motorsport Stage 1 Performance Software for the EA888 Gen 2 2.0T engine running pump gas or ethanol is engineered to safely increase the horsepower and torque with no additional hardware required.

In addition to power improvements, 034Motorsport’s engineers spent a significant amount of time refining the throttle mapping in order to provide improved throttle response and allow for more precise throttle modulation and further control of the vehicle when driving on track. Due to the limitations of the stock turbocharger on the EA888 Gen 2, the rev limiter was not adjusted.

034Motorsport EA888 Gen 2 2.0T Performance Software is flashed via the factory OBD-II port, and does not require any physical modification of the factory ECU. Stage 1 is available in 91 Octane, 93 Octane, and E85. ALL FILES ARE US (MON+RON) RATING, ROW OCTANE RATINGS MAY DIFFER.
