Lowering/bump steer -- further to discussion w/Kris Hansen
<center><img src="http://home.earthlink.net/~dduquette/Audi/audifront.JPG"></center><p>Just to round out this discussion, I found a drawing of our front susp setup (this is from an '05 A4, but close enough for government work ...). You can see it's pretty much like any other car, except that obviously the wheels are driven, so we can't get away with using dropped spindles, etc., like you can sometimes get for a RWD car to get around the bump steer issue.
I am not in the least saying that anyone's wrong that lowering an Audi doesn't give rise to noticeable bump steer, just pointing out that the rack/track rod setup design doesn't really get around the problem. You can see that shortening the springs would indeed make the track rods no longer parallel to the road.
I must say that lowered Audis look so neat. I have a 4.2 sport, which isn't quite as high as some of the other A6s, but it would look great if, say, an inch were taken out of it.
Anyhow, not trying to take a perfectly pleasant discussion and drive it into the ground(!), I'm just purely curious.

Here's the thing, Audi themselves offer the very same cars in various ride heights...
if lowering hte car created noticeable bumpsteer, you'd think lots of people would complain, now wouldn't you?
I would not take that drawing as the gospel either.

There is an adjustment where the tie rod attaches to the bracket to raise and lower it (a little).
You can see the procedure to correct the toe curve in the Bentley alignment section.
Getting this right is the only reason I would go to a dealer for alignment and not needing to mess with this is the reason I just paid only $42 for a top notch alignment on a brand new Hunter machine by a guy who really knew what he was doing.

25.5 inches in the front 26 inches in the rear (ground to fender lip)
The body kit is also about a half inch lower then stock giving a visual apperance that it is lower to the ground as well.

cL, after some thoughts about your recent mod, it struck me that...
you have a few advantages over the RS6 owners. Obviously, you give up on the HP race, but you have a real trunk (no battery stowed there like in the RS6), and you don't have that ugly (sorry) helmet antenna on the roof!
Man, seeing the picture of your car every day is absolutely killing me! Simply perfect!
