034Motorsport is proud to offer the ultimate rear sway bar upgrade for the B5 Audi A4/S4/RS4 Quattro! The 034Motorsport Adjustable Solid Rear Sway Bar is made from high-quality spring steel for maximum rigidity, and is designed to combat understeer while reducing body roll under hard cornering.

This product was tested thoroughly on the street and track on our shop B5 Audi S4 before release. The 034Motorsport Adjustable Solid Rear Sway Bar substantially reduces understeer and body roll on B5 Audi A4/S4/RS4 Quattro vehicles without compromising comfort on the street.

In addition, the 034Motorsport B5 Audi A4/S4/RS4 Quattro Rear Sway Bar is engineered to be used effectively with the stock front sway bar. No upgrade in the front is needed or required. The addition of a stiffer front bar introduces even more push, requiring an even bigger bar in the back. With the stock front sway bar and upgraded 034Motorsport Solid Rear Sway Bar, body roll is virtually eliminated while turn in and off throttle oversteer are greatly improved.

Features:

  • 213% - 330% Increased Sway Bar Rate (Over Stock B5 Audi S4 Rear Sway Bar)
  • 142% - 220% Increased Sway Bar Rate (Over Neuspeed 19mm Rear Sway Bar on the Stiff Setting)
  • 25.4mm Diameter
  • Solid Spring Steel Construction
  • 2-Way Adjustable
  • Designed to be used in conjunction with the stock front sway bar.

What's Included:

  • 034Motorsport B5 Audi A4/S4/RS4 Quattro Adjustable Solid Rear Sway Bar
  • Graphite-Impregnated Urethane Bushings
  • High-Strength Billet Aluminum Sway Bar Brackets

Fitment:

  • B4 Audi S2/RS2
  • 1996 - 2001 Audi A4 Quattro (B5)
  • 2000 - 2002 Audi S4 (B5)
  • 2000 - 2002 Audi RS4 (B5)

Installation Instructions:

Please Note: The use of a rear subframe reinforcement bracket is required with this sway bar. The rear subframe is prone to cracking with an upgraded sway bar, and will likely crack if you attempt to use this sway bar without subframe reinforcements. If you do not already have a subframe reinforcement kit, you must purchase the 034Motorsport Billet Rear Subframe Reinforcement Bracket. This sway bar fits Quattro vehicles only.

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

Works great and is affordable!
Color: Black
Works great! The magnet it comes with is quite weak. But the tool itself works great.

No gimmicks, just a solid WDT tool
Color: Metal Black
This is the second Aieve product I’ve purchased, after a very good experience with their XL espresso cooling ball. This WDT tool isn’t flashy, it doesn’t look like a praying mantis or deploy like a switchblade; but it does exactly what it’s supposed to do. The tool sits in a nicely weighted base that protects the needles from bending, which is a big improvement over the magnetic “floating” styles. The base has enough weight to stay put, and it’s easy to remove and return the tool without it tipping or sliding around. The base itself fits nicely in my tamping station. It also comes with replacement needles, which are simple to swap out when needed. If you’ve been going down the rabbit hole comparing every WDT tool out there, this is a straightforward, well-designed option at a very reasonable price.

Solid 4mm WDT tool with a solid stand and a magnet option for some machines.
Color: Black
Solid WDT tool with good hand feel and convenient counter top stand. 4mm needles and it works fine. 10 of these 4mm needles adequately stir the espresso in the portafilter. No real complaints about build quality. I attached the included magnet. There are many people who have identified that the magnet is not strong. This is true but it depends on the materials on your espresso machine or grinder. On stainless steel units (unpainted or thinly painted) it has good adhesion. On units that might have used thick paint ( which shouldn't be compromised) it may not stick well. So I took a star off--I do have a stainless steel Espresso machine and it sticks fine. It also stuck ok to my refrigerator , microwave and airfryer. If your espresso station is near other appliances---well there you go--also it does show that it "can stick" to fairly common other magnetic materials. My refrigerator is coated in white . I was going to simply buy acupuncture needles, a wine cork and make one of these but add those costs together and heck $9 for this unit with a stand was a great deal.

Great little tool
Color: Black
It’s a cheap tool but can actually make an impact on the coffee. Been using for a few months and still works great.

Great purchase!
Color: Black
I’ve been using the Aieve WDT Tool for a bit now, and overall I really like it. There was definitely a learning curve at first. It took me a little time to figure out how to use it in a way that actually improved my puck prep instead of just stirring the grounds around. Once I slowed down and found a consistent motion that worked for me, I really started to see the difference in distribution. Build-wise, I know some people have mentioned the stand falling off. Personally, I haven’t had any real issues with it unless I’m the one who bumps it and sends it flying. If it’s staying put and I’m not being clumsy, it’s fine. I’m using the magnet side to stick it right to my Breville, which has been super convenient. It keeps everything within reach and makes my workflow smoother. For the price, it’s been a solid addition to my espresso setup, especially now that I’m getting the hang of it.
