034 Motorsports Full Density Line Control Arm Kit (Late - M14) B8 | B8.5 Audi A4 | A5 | Allroad | Q5The factory front control arms are an integral part of the B8 B8. 5 Audi A4 S4 & A5 S5 RS5 suspension, but can start wearing out as early as 40,000 miles especially on enthusiast owned vehicles which are driven hard on the street or track. As the rubber bushings degrade and ball joints develop play, alignment is compromised and steering becomes less precise. 034Motorsport's complete Density Line Control Arm Kit is designed to be a performance

The factory front control arms are an integral part of the B8/B8.5 Audi A4/S4 & A5/S5/RS5 suspension, but can start wearing out as early as 40,000 miles - especially on enthusiast-owned vehicles which are driven hard on the street or track. As the rubber bushings degrade and ball joints develop play, alignment is compromised and steering becomes less precise.

034Motorsport's complete Density Line Control Arm Kit is designed to be a performance replacement for all eight of the factory front upper and lower control arms. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line Control Arms are engineered to limit unwanted deflection in the suspension, resulting in tighter handing and more precise steering response than even brand new factory control arms can offer.

Features:

  • Complete, Drop-In Replacement for Factory Control Arms

  • Offers Improved Handling Feel & Steering Precision

  • High-Durometer Rubber Bushings (65 Durometer)

  • Includes New M14 Ball Joints

Please Note: New Outer Tie Rod Ends are sold separately.

Installation Note: 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.

Founded in 2005, 034 Motorsport is driven by the passion to bring motorsport-quality performance products and tuning to your Audi and Volkswagen vehicles.

Quality Material, Comfortable Fit
Size: Medium, Color: Emerald Green, Size: Medium, Color: Emerald Green
I often have trouble with sports bra bands feeling too constricting (for size 34C), but this one was comfortable enough to wear right away and I can tell it will get comfier as I wear it. I am 5’7, 130 lbs and bought a medium. The color is vibrant and the material feels high quality. Straps are not adjustable but that hasn’t been a problem up to this point.

Good price, does the job
Size: Large, Color: Emerald Green, Size: Large, Color: Emerald Green
I love the way this fits. I’m probably a C cup on a good day and just under 200 lbs. I wear this for my workouts (elliptical and weight lifting). It stays in place, has kept up in my chaos washing, and is super cute.

Cute but not very supportive
Size: Large, Color: Navy
This bra is cute but it’s not very supportive. I’m a 34DD and it gaps on the sides and the straps are too long even though I have a long torso. I’m not even sure that I’ll wear it low impact activities, probably just day to day wear.

Cozy for Sleepwear
Size: XX-Large, Color: Emerald Green
I bought a plum thermal union suit, but it has actual buttons. So I bought this bra, so I could leave some of the top buttons undone for quicker trips to the bathroom while also giving a nod the color combo of the Quetzal bird.
