Nice color, Bob. Not sure I like the wheels on this application...I would go with Hobby Design's 20 inch wheels (the optional wheels on the DBS).
Also, when you're mixing and matching tires, are you getting the same tread? I've been having trouble finding the right size front and rear tires for my Revell SuperAmerica wheels that I'm going to put on my 360 spider.
We need a manufacturer to create just tires!
