I would like replace my GTV-6 wheels for a new set. I do not know what is the best size; 16x7 or 17x7. If anyone has experience with the larger size wheels, I appreciate the input. My car is a street car with occasional track use. I like the general feeling of the original car and would like to maintain it as much as possible. It is hard to find tires for the original wheels with strange metric size.
