We're proud to announce the availability of our improved Motorsport Differential/Transmission Mounts for most early Audi applications, including the B3 Audi 80/90/Coupe Quattro, Audi UrQuattro, Audi 4000/5000, Audi 100/200, and Audi S2/RS2!

034Motorsport's Motorsport Differential/Transmission Mounts are the new standard in track performance. Our mounts are engineered with racing in mind, and manufactured from billet aluminum and delrin for the ultimate in performance and durability.

The result is a locked-down drivetrain, solid shifting, and virtually no wheel hop. Motorsport Drivetrain Mounts will cause a noticeable increase in noise, vibration, and harshness (NVH) inside of the cabin. Our Density Line Mounts are better suited towards street-driven vehicles on which excessive noise and vibration are not desired.

Features:

  • Manufactured from Billet Aluminum and Delrin
  • Rebuildable Design
  • Includes New High-Grade Metric Hardware
  • Reduced Drivetrain Slop
  • Decreased Differential/Transmission Movement Under Load
  • More Direct Power Transfer
  • Improved Shifting Feel
  • Complete Drop-In Replacement of Factory Differential/Transmission Mounts
  • Sold Individually (2 Mounts Required Per Car)

Fitment:

  • B3 Audi 80/90/Coupe Quattro
  • Audi UrQuattro
  • Audi 4000/5000
  • Audi 100/200
  • Audi S2/RS2
    • Only replaces factory transmission mounts on later B4 chassis vehicles which use the B4/B5 style rear differential mounts.

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!

4/5 Stars
Size: 4 Panel-88'', Color: Black
Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.
