Car: 11 Audi TTS

Mods: 19" OZ Wheels w/ 255/35/19 rubber and K&N Filter

Issue: Although it is mainly driven on the street I do track my TTS down here in Southern California. Whether driving the canyons(ie Topanga/Decker/Mullholland) or running the Tracks(ie Chuckwalla, Willow Springs, AutoClub, etc) I have a lot of body roll. This creates a horrible sound of the rear inner fender well rubbing against the rear tires. I was told that with a good Rear Sway Bar this would stop and improve my track times.

Question: I am not looking to just go out and buy the most expensive or the cheapest Rear Sway bar. What would be the best quality/most efficient Rear Sway bar for my car with the given conditions and issue? Should I also get the front sway bar and associated support brackets/links?

Thank you in advance!

I went with the Nuespeed rear swaybar and my rubbing went away, 2012 TTS.

Did you get a chance to research/review any others before purchasing the Neuspeed one?

What size is yours and do you know what sizes actually fit on ours?

I have seen H&R advertise a 21mm and 22mm, the Neuspeed I have seen advertised is a 25mm, websites make it look like Whiteline's 22mm generic one will fit, and 034 Motorsports also has a 22.25mm swaybar that supposedly fits... honestly not sure how all these different sizes would fit and what the advantage of a smaller 21mm vs a larger 25mm would be if they actually do?

The Nuespeed is hollow so that's why it is a larger diameter. I found a website that had all the swaybars and their stiffness more than OEM in percentages but I can't seem to find it now. I do remember the H&R was the stiffest though. To be honest I went with the Nuespeed because it was red(matches my car) and I could get it fast because I ordered only a few days out from a track day. Like I said it made a huge difference in the softer position.

Neuspeed also. Stiffer position. Big difference.

I also remember reading the diameter did not indicate stiffness because either some or all were hollow. The Neuspeed ships with bushings which are the only items needed to accommodate the difference in diameter.

If I remember right from my research the Nuespeed is the only hollow one available for the TTS the rest are solid bar stock.
