First of all I sincerely apologise as I am sure you are all sick to death of this sort of query! I have been BMW for the last 8 years and have finally made the big switch to Audi.. Treated myself to a very nice spec black 2009 A4 S-line 2.0 tdi automatic.. (As seen in the attached image).. Lovely car inside and out. I am toying with the idea of changing the alloy wheels to a 19" something or other, with the RS4s really catching my eye (example image of white car attached).. Anyone have any recommendations for me to take a look at? As always images would be appreciated.. Need as much help as possible from experienced Audi enthusiasts Cheers guys.
