He doesn't advertise this as far as I know, but Doug Lepak can convert a non-wood grain wheel to wood grain.

He even made the wood on my non-wood wheel match the console and instrument panel wood grain decal sample I gave him. He also made the rim a bit fatter than original, which I think is better.

To duplicate the appearance of the metal sandwiched in the middle of the wheel rim, he laid in what appears to be a thin strip of metallic Mylar. However he didn't get it in the same plane as the spokes. It is "floating" in another plane above the spokes. If you ask him to do this, be sure to request that the metal be in the right place.

First photo is my original green colored wheel. Second photo is another wheel showing the metal rim is in the same plane as the spokes and attached to the spokes. Last photo shows my converted wheel with the "metal" rim floating above the spokes.
