That's a great way to get a chassis done. On your tires, I don't know if you're familiar with the AMT tires from Round 2 ? That seems to be the measurements of there 8 tire Racemaster Slicks kit. They offer Wide Whites, one side only, Whit Letter, Narrow White Walls and White Wall with a Red Stripe. They have the "Pie Crust" design if that will help.
