If you're looking to really dial in the handling of your B5 Audi A4/S4/RS4 Quattro, you might want to check out the 034Motorsport Adjustable Solid Rear Sway Bar. This isn’t just another upgrade—it's a game changer. Crafted from high-quality spring steel, this sway bar is built for serious rigidity. What does that mean for you? Less understeer and a noticeable reduction in body roll when you're pushing your car through those tight corners.
I’ve had the chance to put this sway bar through its paces on both the street and the track, and let me tell you, it delivers. The difference is night and day. You can really feel the car responding better, especially when you're on the throttle. It keeps the rear end planted without sacrificing comfort for daily driving. You can take those sharp turns with confidence, knowing the body roll is kept in check.
One of the best parts? You don't have to worry about upgrading the front sway bar. This rear sway bar is designed to work seamlessly with the stock front setup. It’s all about balance—adding a stiffer front bar would just push you into needing an even bigger rear bar. Stick with the stock front sway bar, and you’ll find the perfect harmony with the 034Motorsport rear sway bar. Trust me, it really sharpens the turn-in response and helps with off-throttle oversteer.
When you purchase this sway bar, you’re also getting some solid components to go along with it. Included are graphite-impregnated urethane bushings and high-strength billet aluminum sway bar brackets, which means you’re getting durability right out of the box.
Just a heads up: if you’re thinking about this upgrade, make sure you have a rear subframe reinforcement bracket. The last thing you want is to risk cracking the rear subframe with all that added stiffness. If you don’t already have one, you’ll need to grab the 034Motorsport Billet Rear Subframe Reinforcement Bracket. Oh, and this sway bar is specifically for Quattro vehicles, so keep that in mind.
For those of you who have lowered your ride, just be sure to check clearances across the full range of suspension travel. I highly recommend pairing this with 034Motorsport suspension components—they’re designed to work together without any interference.
Fitment:
In short, if you want to take your B5 Audi to the next level in terms of handling, this sway bar is definitely worth checking out.
