Having two sets of wheels is worth considering. I would define my car more as a road registered track car than a road car that some times is used on a track. The car is set-up for track use not road comfort, and I would say it would be uncomfortable to use on long road trips - I have the family Grand Voyager for that

I know the regulations are vague. They basically say that you can put any wheel and tire on the car that will not alter the factory set overall dimensions, which I can understand on a road car - they do not want the speed reading to be wrong!

Ideally I would have two sets, but I will probably dump the Speedlines and replace them with a set of BBS wheels - all I need to know is if they should be 16", 17" or 18" ones to give best performance on a track?
