exactly!! Nice, you are observant!!The S4 lower will fit but it sticks out slightly at the bottom, not flush with the bumper, if you look closely at one of the earlier pics you can see it's not flush but still looks good.
Nice wheels, not 'that' different from the Rs4 reps though?
the RS4 were OEM. These are CSL BMW!
Yes I realise that. My point being they are a spoked alloy which look similar to what you had before, ie 8 twin spokes vs 7 twin spokes.
You said they were 19 x 8.0j. OEM RS4 wheels are 9.0j aren't they?
