New 19 x 9.5" VMR V713's and 265/35/19 PS2's installed using 15mm spacers:
Thanks to Kevin and Sam at Imola Motorsports in Minneapolis, MN!... They were very patient, informative and knowledgable during the selection process and quite diligent measuring fitment and calculating spacer and tire size. I am very pleased with the look and function---we were a bit concerned large spacer's would induce wobble/vibration. None. Perfect. Also, glad they conviced me to pony-up extra coin for Michelin PS2's---these tires really are worth the extra cost!
I think the wheels update and compliment the C5 wide-body styling... Ironically, Imola had another RS6 in for service while mounting my wheels/tires today... So, I took the liberty of taking some pics of the two side-by-side.
