Our first prototype B6/B7 Audi A4/S4/RS4 Solid Adjustable Rear Sway Bar is ready for testing!


After great success with our Audi TT RS Rear Sway Bar, we started development on an affordable, performance-minded rear sway bar upgrade for the B6/B7 Audi A4/S4/RS4 Quattro.

While the OEM RS4 Rear Sway Bar Upgrade is very popular, we feel that it leaves a bit to be desired in terms of performance. Combined with the rising price of Genuine Audi parts, we will soon have a much better alternative available.

What we ended up with is a bar that's adjustable from 100% to 124% stiffer than the stock B7 Audi RS4 Rear Sway Bar.
