19inch wheels rub on Euro S Line springs. These are 30mm lower than standard and 10mm lower than sport.

Go steady if you have the S Line springs and 19inch wheels. Across Europe audi would only let you order 19inch wheels with "Sport" suspension and not " SLine "Suspension.

We get three configs over here

Standard setup found on Entry and SE models
20mm Sport available on S Line models as default
30mm S Line free request on S Line package but not allowed 19inch from Audi.

I understand that the US package for S Line and Sport is different than Europe to see what springs you have first.
