its not so much the size of the wheel as much as the weight.
Reducing 5 pounds at each corner on such a small car and engine will make a huge difference.

My old miata originally had I think 14" wheels, with hollow spokes. I went for cooler looking but heavier 16" BBS RK's and the difference was night and day. THe car was allot less nimble and direct. Once I mounted the lighter autocross wheels it was back to its old self.
