Wrong.
I'm going to remove one wheel from an RX8 and test fit it on my car.
I've purchase 3 brand new cars from this dealership, and thy have made small changes/modifications for my new cars in the past. So I'm sure it will not be a problem.
I know what I'm going to do: I'm going to go to my local Mazda dealer and I'm going to ask them to let me test fit and Rx8 wheels on my Atenza. I'm sure it would not be a problem.
By the way, I just found these on ebay...
My choice:
205-45-16
1.- Michelin Pilot Exalto PE2 = $143 (if you are serious about street performance) summer
2.- Yokohama Parada Spec-2 = $80 (best performance-value) summer
3.- Pirelli PZero Nero = $84 (best all season performance and value) all season
Hope this helps.
