I'd love to have a subtle side skirt without having it's lines be excessively lower than the S-Line bottom body line. Make sense?
Here is an example of the the DTM kit for reference. This car has the front DTM bumper. (And if I'm not mistaken there is not a DTM rear for Avants. And looking at the lines, from back to side, things line up well.)
