He didnt have the specs with him today. I asked him to fax it to me so I could take a look at it. I'll keep you posted.

Just curious, is there any way to dial in more negative camber for better turn in?

Total camber is fixed. The only way to adjust it all all is to shift the subframe, but adding more negative camber to one corner means more positive camber on the other side. The S8's camber specs are

Front: -1^o35' to -0^o35'
Rear: -1^o10' to -0^o10'

Some tuners have adjustable links for the upper A-arms to allow adjusting camber, but I've only seen them for the A4/S4, not the A8.

Also, I think the front end could use some additional caster, which runs only about 3^o. I tend to wear out the inside of the right side tires only, and with mostly right turns on the track, those are the lightly loaded tires and ideally should have positive camber.

Even from the angle of this pic, you can see how body roll has given the inside front tire way too much negative camber. I think about 8^o of caster would go a long way to correct this.

The specs are a range, not with a "+/-" as I originally showed.

Just what I suspected. front total toe was -0'13 and the tollerance is 0'10 to 0'30 and was set now to 0'20. the rears was 0'04 and tolerance is 0'02 to 0.22'. The rear was at the lower range so I suspect thats why the cupping showed up after the first rotation.
