I'm running 18" x 8.0J, with an offset of ET42, with 10mm spacers, making them ET32. Wouldn't want to go any lower - that's about the limit on a 'standard' B6.
Not sure about the S4 - maybe it has wider arches to accommodate a smaller offset.
The reason I asked, was that I had seen a set of 16" alloys which would of been ok for winter but they had a offset of ET31 so wasn't sure if they would fit or not.
