Ideally...I agree and that is the obvious answer. However, the Arc 8s won't be dedicated because I won't use them enough to justify them and frankly for daily driving and playing around on the road, the stockers don't cut it. I'm not that serious about track and need to keep that way.
The other thing I noticed was that tires are cheaper for the 17s...yes they are 17s, and I can do a set of NT01s for about $600.
The other "debatable" point is that the stockers would be a square set up....say 225/40/17 for less understeer.
So the question is...if you were going to the track and had 2 sets of wheels as I've described, which set would you put on?
