ok...i know i might be stirring it up a bit, but.....
by installing this I have heard that it should remove the oversteer...others say that it makes the car a little too dangerous because of the oversteer removal. Is the danger the drivers ability, or lack there of???? I want to jump in on this group buy, and not worried about my ability....but if it makes the car too unstable that is different....
Sorry if I am bringing up a sore subject...but i really want to understand the dynamics here.....
TIA

Here's some info...
The link below will take you to a post regarding a TT with said sway bar which crashed. Here are some follow up comments from me (aka Brad Willis) and Chris Lloyd (aka Lloyd of the Rings)...
Are we sure this Neuspeed bar isn't TOO thick? After all...

When Audi made the changes from MkI to MkII, they only modified these bars by 1mm. Here, we're talking about about a 5.4mm change, which seems substantial.
Are we sure we aren't overdoing it, i.e. reducing understeer to the point that the car could be potentially dangerous and the odds of the back end coming around increasing dramatically? We all want to improve handling characteristics, but not at the expense of safety.

My feeling too. Wes Simpson has the only TT I know with this change and .......

significantly (in my mind) he spun at both SearsPoint and Thunderhill track days. I think this large a diameter bar might induce too much oversteer.
Personally, I find the TT to be fairly neutral in handling; a larger diameter rear anti-roll bar would certainly increase the likelihood of the back stepping out with abrupt off-throttle changes.

That's my gut feeling. In other words, I think we have to be careful about saying, "Neuspeed makes a 19mm bar, so let's throw it in there and see what happens".
At one point, I was going to swap my MkII rear bar with a MkI rear bar. I still have the feeling that this would have been a nearly ideal setup. But again, we're only talking about a 1mm difference overall. Ultimately I decided against this.
When I owned a MkI TT, I almost swapped ends and lost it once. Fortunately, I was able to counter and recover, but if I had spun, I could have been injured and the car may have been damaged. The MkI TT did not feel like I was beyond the limit until I was actually there.
Since I have been driving my MkII TT, this has not occurred. I'm sure that part of that is due to being a better driver now, and more familiar with the TT's handling characteristics. But I also suspect that the understeer that Audi introduced has indeed made this a safer car.
Again, my gut feeling is that leaving the MkII's front bar as is, but swapping the rear with a MkI (1mm increase) would be a compromise mid-point (if that makes sense) between a MkI and MkII with respect to anti-sway bars. I also have the feeling that a 5.4mm increase in rear diameter is potentially dangerous.<ul><li><a href="https://forums.audiworld.com/tt/msgs/385481.phtml">Sway Bar Modifications</a></li></ul>
