I am talking to my dealer about ordering 336 wheels and swapping them for the 214 wheels when my car arrives since they are not available as on option in the 35i. I am waiting for a swap price. Does anyone know the difference in dealer cost between the two wheels? Any opinions on a fair upgrade price? Since they are the same size I just plan on using the stock tires so my question is what is a fair price to trade just the wheels.
