Looking to purchase some new rims for my a4 the 17's just arnt cutting it and with the R8 style headlights and HIDs the stock rims just throw everyting off balance. I was looking in to getting some R8 replicas off that OEWheelsLLC.com but not sure what size would look good...18s?, 19s?, 20s? since my cars red i was thinking a gunmetal grey or a black for the color...whats your opinion?
