034 Motorsport - Adjustable Rear Sway Bar - Audi B9 A4/S4/A5/S5/RS5 034-402-1010.

* Fits Audi B9 chassis 2.0 TFSI and 3.0 TFSI.

034 Motorsport is proud to offer the ultimate rear sway bar upgrade for the B9 Audi A4/S4, A5/S5/RS5, and Allroad! The 034Motorsport Dynamic+ Adjustable Rear Sway Bar is made from a single piece of high-quality, 22.2mm thick spring steel for maximum rigidity, and is designed to combat understeer while reducing body roll under hard cornering.

All 034 sway bars are solid - do not choose your sway bay on diameter alone!

This product was tested thoroughly on the street and track on 034Motorsport's in-house B9 Audi A4 Development Vehicle before release. The 034Motorsport Dynamic+ Adjustable Rear Sway Bar substantially reduces understeer and body roll on B9 Audi A4/S4, A5/S5/RS5, and Allroad vehicles without compromising comfort on the street.

In addition, the 034 Motorsport Dynamic+ Rear Sway Bar is engineered to be used effectively with the stock front sway bar, and maintains factory levels of comfort and driveability. No upgrade in the front is required with this rear sway bar. The addition of a stiffer front bar can positively affect turn-in feel, but ultimately worsens the platform's tendency to understeer. With the stock front sway bar and upgraded 034Motorsport Solid Rear Sway Bar, body roll is substantially reduced, while turn in and off throttle oversteer are greatly improved.

Super wide

They are oddly very wide. Great for kids with wide chunky feet but for us it was not cute

Solid Kids Sandals, Overpriced Like Most Kids Shoes 🌞
Size: 11 Little Kid, Color: Brown, Size: 11 Little Kid, Color: Brown
My son hasn’t worn these yet since it’s December in Indiana and sandals + snow obviously don’t mix. 😂 So this review is based on first impressions rather than long term wear. That said, these seem wider than a lot of typical kids’ sandals, which I REALLY appreciate since we tend to have wider feet in our family. #hobbitfeet The quality feels pretty decent overall. They’re described as lightweight, and while they’re not insanely lightweight, they do have enough weight to feel semi-sturdy and not flimsy or cheap. I like the style and color, and I think they’ll work well for my son once warmer weather hits. My main complaint is the price. At just under $24 at the time of this review, it feels a little high for kids’ sandals and for what these are. I really feel like $20 MAX would make more sense. Kids shoes are almost always priced like adult shoes, even though they clearly use less material, and that’s hard for me to understand and wrap my mind around. Overall, these seem solid for daily wear, I just wish the price was a bit more reasonable and affordable.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play. The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far. They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!
