If you're looking to seriously upgrade your B9 Audi A4, S4, A5, S5, RS5, or Allroad, you might want to check out the 034Motorsport Dynamic+ Sway Bar Kit. Trust me, this isn't just another aftermarket part—it's a game changer. I've had my hands on this kit for a while now, and I can tell you that it really takes your handling to a whole new level.
First off, let's talk about what you're getting. This kit includes both front and rear sway bars made from high-quality spring steel, which means they're built to last and handle whatever you throw at them. The front sway bar has a 28.6mm diameter and a solid 0.250 wall thickness, which is a noticeable step up from the factory's 28.19mm bar. That 49.2% increase in sway bar rate makes a big difference when you're cornering hard. You’ll feel the car stick to the road like it’s glued down.
Now, the rear sway bar is where things get interesting. It’s 23.8mm in diameter and comes with a two-way adjustable feature. You can set it to soft for a 259.3% increase in sway bar rate or firm it up for a whopping 305.8% increase. This flexibility means you can dial in your ride for the street or the track, depending on what you’re after that day. Just keep in mind that going with this kit will give you a firmer ride than the stock setup, so if you’re all about comfort, this might not be your first choice.
Installation is straightforward, and the kit comes with everything you need: the sway bars, polyurethane bushings, billet aluminum brackets with integrated Zerk fittings for easy greasing, and all the necessary hardware. If you’re like me and enjoy getting your hands dirty, you’ll appreciate how simple it is to swap these in.
Now, a little heads-up: if you’re planning to drop your ride, make sure to check all your clearances during full suspension articulation. I’ve seen it happen where folks get a little too ambitious and end up with some interference issues. I’d also recommend pairing this sway bar kit with spherical end links for the best performance. They work seamlessly together and really enhance the overall feel.
To sum it up, if you want to transform your Audi’s handling characteristics and feel a more connected experience behind the wheel, the 034Motorsport Dynamic+ Sway Bar Kit is worth considering. Just remember, it’s designed for those who are serious about performance and are ready to make that shift from comfort to a more sporty ride.
