Yes sir, realize all of this. I will repeat my post a bit; ....I am more or less hoping to find someone with the "experience" of doing just this already to chime in. I do not have the new rims I want to buy in front of me, (they are VW rims, not aftermarket...) I will agree with the fact that it is the calipers and this inside clearance that is my only critical concern. Thanks for answering. Anyone doing this on their R Line?
