The rims are Advan Model 5. They are discontinued now but there is Advan Model T5 as a replacement. It looks pretty much the same, but the twin-spokes of the new T5 is more spaced-out than the older Model 5.
There are no deep-dish/no lip for these rims and this is how I wanted it. I wanted concave wheels. I wish mine was more concaved though, but since they're discontinued I really didn't have much choice.
Hope this helps.
