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.

Beware the shrinkage
Size: X-Large, Color: Chill
This shirt came looking as expected and the quality was good but it ran a bit small. I had to give it to my dad and it looks great on him!

NOT EVEN CLOSE ON SIZE!!
Size: XX-Large, Color: Light Blue
I'm not a small guy...im rather robust like a good Italian dressing..and this shirt is 100% disproportionately wrong! If your thinking 3xl sounds good for the price DONT BUY IT!! At best this is an XL t-shirt with a 3XL tag. I can't return it because I immediately cut tags off my shirts..I know weird right lol. Anyway hopefully you read this and like ex-relationships you 'MOVE-ON'!!!!!
