I saw those, but they're not quite it. Those wheels have a rounded "spoke", whereas the ones in the ebay auction have a lot more of an "edge" to them- especially where the spokes blend into the center section. The ones on the website also have more of a curve where the spoke meets the rim.
Are those supposed to be the same wheel, just a difference between manufacturers?
They look similar, but as you stated they have comparable differences. I believe the wheelenhancement rims are genuine but a variation of the style on ebay. If you can't place a rim.... http://www.wheelenhancement.com/index.php?t=Wheels
He mentions on the site that they're replicas from Japan. I sent him an email to see if he has any more information. Again, you can see that they're different than the ones on the wheelenhancement website.
