The BBS vz are somewhat similar to the B7RS4. Was it the B7 RS4s that you were thinking of? I would not spend the money on new wheels for such a small change in looks unless, you want the 17" ers for the winter and the 18" for the summer. One thing that I did not consider when upgrading my previous A4's wheels was the weight and its effect on power and handling. Now that I am moding an S4. I am more concerned with wheel weight. Just thought I'd mention it.
