Those rims I currently have with my 17" A/S setup that I am using during the winter months in NC, the rims are not for sale. If you're worried about which rims to get with these, there are plenty. The size of those rims is 17x7.5 offset 45 They werent very expensive, look on TireRack or DiscountTire as thats where im pretty sure I found them.
Price stays at $400 picked up, shipping will be extra and its still a very nice deal for winters with very little wear
