They aren't listing all the sizes for the mesh wheels. I wonder if they can get the 16x8 0 offset and 17x8 and 9s SSR lists in Japan. The price on the Japan site lists prices in the $400-500 a wheel range though, so they can't be very cheap.
The Formula Mesh are beautiful. Almost exactly the same centers that are on my car. I like the way the center is not filled in and not flush with the mesh around the middle. I also like the way it is flat not convex in the center.
