I'll follow up too... I bought crowtrobot's old stock wheels
I am very satisfied with having two sets of stock wheels, which I can make two square setups now. I did a track day about 2 weeks ago on the square tires that were mounted on the wheels I got... the car was very balanced. Someday down the road I'll probably also end up with EC7s (if not another Miata).
Overall this seemed to have worked out perfectly for both of us!
