Street Density Transmission/Gearbox Mount Upgrade, B8/B8.5/B9 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5

The 034Motorsport Street Density B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & B9 Audi A4/S4/Q5/SQ5 Transmission Mount Upgrade is designed to improve the performance of the factory transmission mount assembly with a high durometer rubber mount replacement. This part is a direct, drop-in upgrade for the factory rubber damping medium used at the rear of the transmission mount assembly. In conjunction with other 034Motorsport Drivetrain Mount Upgrades, the Density Line Transmission Mount further reduces unwanted drivetrain movement to ensure that you experience improved throttle response and more direct shifts.

Please Note: Installation of this upgrade will result in increased noise and vibration transmission into the cabin, especially in vehicles equipped with the Tiptronic transmission.

We highly recommend purchasing our Billet Aluminum B8 Transmission Mount Insert Upgradealong with this part to minimize unwanted drivetrain movement!



034Motorsport is proud to offer our Street Density Transmission Mount Upgrade for the B8/B8.5 Audi A4/S4/RS4 and A5/S5/RS5 & B9 Audi A4/S4/Allroad & Q5/SQ5! The factory Audi transmission mount assembly features a soft rubber damping medium, which allows for excessive transmission movement at increased power levels, and can break down over time. This movement can be observed as hesitation or lurching when accelerating, decelerating, and shifting.

This high durometer performance mount upgrade is designed to be a direct, drop-in replacement for the factory damping medium, and limit unwanted transmission movement. By reducing slop, this upgrade ensures that you’re experiencing crisper shifts and a more connected driving experience. This upgrade will introduce some additional, perceivable increase in noise and vibration transfer into the cabin, especially on vehicles equipped with the Tiptronic transmission.

In addition, the factory transmission mount assembly components are not available separately from dealerships, and premature failure of this mount can result in having to buy the entire assembly. The Street Density Transmission Mount Upgrade from 034Motorsport lets you reuse the factory cast portion when replacing/upgrading the stock mount.

This mount was thoroughly tested by 034Motorsport, and independent Audi enthusiasts before release. Installation is very straightforward, and is completely reversible.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.
