Avus is right in my backyard. A good friend of mine knows the owner. I was at their warehouse when they made some wheels for his Supra. They let him piece together a wheel configuration custom to his car. From what I understand, he has the widest wheel on a stock bodied Supra. These are good guys.
All their centers can be had in black chrome and gunmetal. I think the Viper pictured would look great with either of those finishes.
