The 18's will slow you down. I have 18 inch wheels/tires that are 39lbs total while the stock wheels are 40 lbs total. I loose 2 tenths and 2mph on avg if I run the 18's. They are the same overall size and they are lighter but they still slow me down. The weight is more towards the outside edge of the rotating wheel and they are harder to get moving. If you have your stockers you will will drop down.
But I bet those 18'' look nice. I would gladly trade .2 tenths for some nice looking wheels.
