2006 a6 vs S-line suspension components

[type911]

Curious, what the difference in rear suspension between the two. Wondering if aftermarket wider wheels can be interchanged. If it was fine on the s-line would it be ok on the a6?

Cheers

no diff in wheels form one to the other... Some regular A6 had trhe sport suspension like S line....
stiffer suspension, a bit lower, and bigger/stiffer sways I think

yeah and a stock S-Line rides like there isn't springs on it, it sucks, it hit way harder on bumps than my Koni's and Ebach's.
