If you found a good place to make the adapters they will know the hub bore of a miata . Look on the wheel for a sticker that shows the wheel size and offset . If there isn't a sticker some wheels stamp it on the back of the wheel . If that isn't there take a tape measure and try and get close as you can they look that up and see what is the closes .
As for the wheels run the rears on the front with a 25mm adapter and get a larger lip for the rear on the 7 . with the same adapter
