034 Motorsport Audi A4 B4/B5 - Motor Mounts, Street Density - B4, B5 A4/S4

We are VERY excited to be announcing the release of our 034Motorsport Street Density and Track Density motor mounts for a wide range of Audis!

We've been testing these mounts for some time to ensure they are reliable and meet the criterion for the intended use - results so far are very exciting!

WHAT THEY ARE: A new line of rubber motor mounts made FOR us by OE suppliers to OUR specifications.

STREETDENSITY Mounts are solid rubber mounts with a 50 durometer about 10% stiffer than stock, this means they still ride smooth and quiet but provide a marked improvement in drivetrain dampening over stock mounts. Livable street performance with serious sport intentions. Note, since there are no voids or air pockets in these mounts, even though the rubber is only 10% stiffer, the resulting reduction in drivetrain movement is actually 25% stiffer.

TRACKDENSITY Mounts are also solid rubber mounts, but with an 80 durometer approx 90% stiffer than stock, these are solid for all practical purposes and result in ZERO drivetrain movement. Vibrations from the engine are noticeably increased but not horrible. Definitely not smooth and quiet like stock mounts, but in return you get a completely locked down drivetrain with NO slop or deflection. These are perfect for the street/track enthusiast who doesn't mind a marked increase in vibration from the drivetrain.

NOTE, THIS IS NOT AN OE MOUNT, OR AN RS4 MOUNT, AND ARE NOT AVAILABLE FROM ANY OTHER SOURCE - These are built by an OE supplier to 034Motorsport specifications.

We have tested these mounts on our own B5 1.8t quattro for over 10k road miles and 6 track days, upon recent removal they still looked like new..

These mounts replace the upper differnatial carrier mounts, the 2 small bushings that press into the carrier that holds up the rear diff.

Mounts will fit all B4 and B5 chassis cars including A4/S4, A6, 90 Quattro, RS2 and many other applications (does not fit Passat), feel free to contact us for clarification.

Choose stiffness below, price PER PAIR for one car.

Not bad. Not great.
Size: 5 Panels, Color: Grey
This was very heavy. It wasn't too hard to assemble but you do need two people. Sadly did not help with the noise I was hoping it would. For the money I spent I was hoping for more.

It has no sound insulation function at all
Size: 5 Panels, Color: Grey
I purchased this soundproof partition with the expectation of creating an independent and quiet office environment. However, the product does not deliver effective sound insulation. The ambient conversation noise outside the partition measures 50 decibels, and the noise level inside remains unchanged at 50 decibels. Given this lack of performance, I would like to inquire about the actual acoustic value of this partition. This constitutes a clear case of misleading advertising.

Partition Divider
Size: 5 Panels, Color: Grey
The Natwind 5-panel portable partition is ideal for creating privacy and dividing office space. At 122.8" x 71", it provides substantial amount of coverage, and the folding design makes it easy to set up, move, or store as needed. The freestanding structure is stable. The acoustic panels are quite thick at about 1/2in thick and help reduce noise. Its neutral color and design blends well with most office interiors. Overall, this partition is a convenient and effective choice for temporary or flexible workspace layouts.

Great quality, easy to set up.
Size: 3 Panels, Color: Grey, Size: 3 Panels, Color: Grey
I actually have this in my bedroom, replaced a non acoustic panel with it. These make a huge difference. As someone who is always playing music on their speakers I don't want to bother my roommates too much. Easily can hear the difference once these were in place. The panel itself is high quality and thick, what's a really nice detail is how they are attached together, there are multiple wedges just like foam noise dampeners which is super cool! This thing is easy to move around and can be folded for storage with ease. You get extra screws just in case you lose any, the feet are made out of metal which adds to the quality. There was a very slight chemical smell when taking it out the box, however that went away in just a few hours. I can imagine using this in a noisy office, surrounding yourself with these in a cube shape will make all the difference to focus on your work. These panels are great and if you're looking for quality, I'd say you can pick these up without worry. No issues on my end!
