I have a 2007 S8. I certainly dont want to put winter tires (in Montreal) on the oem 20" mags. Audi sells a 19" set with winter tires - for $1000 per wheel! However there is a much less expensive 18" set for the A8. So - does anyone know if the A8 18" mags fit on the S8 (2007). The break callipers are certainly an issue...thanks
