034Motorsport's Density Line Adjustable Upper Control Arm Kit for B9 Audi A4/S4, A5/S5/RS5, and Allroad replaces the fixed factory front upper control arms to allow for precise, independent camber adjustments.

Density Line Adjustable Upper Control Arms for the B9 platform are available in two versions depending on your specific needs: Camber Correcting to add positive camber to reach factory alignment specifications and reduce tire wear after lowering, and Track Spec to gain additional negative camber for increased cornering grip and improved handling performance.

INSTALLATION & WARRANTY

Installation:

  • It is imperative that the suspension be compressed to static ride height before any suspension pivot bushings are tightened, as per the factory installation procedure. If this is not done, the bushings will tear prematurely as the twisting forces on them will be much higher than is intended. 034Motorsport's Limited Warranty on Density Line products does not cover premature failure due to improper installation or use.
  • We highly recommend professional installation for this product.

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.)

Warning, if you have two different thickness of monitors these may not work as intended.
The product seems very well made and the adhesive is very strong. These seem like they would work really well if you have two monitors of the same thickness, in my case I did not and they actually created more of a gap then without.

Pretty cheap but surprisingly solid
Color: Black
This thing comfortably fits my 16” MacBook Pro. It does tilt a bit probably due to me screwing it to the underside of my wooden desk which probably isn’t the exact use for it, but it holds really strong and isn’t going anywhere. Combining this with a small USB-C hub for some USB As and and extra HDMI and a little bit of Velcro, this holder makes for a pretty solid option to hide you laptop away if you a surprisingly clean desktop-like experience, even if you’re on a budget and can’t afford a desktop. A proper thunderbolt docking station would go a long way with this as well.

Works as advertised
Color: Black
Functions as described. Looks good. Laptop fits in loosely. I’d prefer a more snug fit. Other than that, works as advertised.

Genius solution for a cleaner, more organized desk
Color: Transparent, Color: Transparent
This mount completely transformed my workspace. I was looking for a way to get my laptop off my desk without buying a whole new piece of furniture, and this delivered. The clear design blends into any space so it doesn’t look clunky, and installation was easier than I expected. My laptop is secure and easily accessible, and I’ve freed up so much desk real estate. If you’re trying to create a cleaner, more minimal workspace, this is a great purchase. We did have to screw it in place because the sticky side came off after a few days, but I think it’s just the temperature fluctuations in my office.
