Don,

I assume you are saying the wall thickness is illegal. So, what size wall thickness is it and when was the car constructed?

The car still has to pass a minimum weight. So other than a safety issue and a USAC rule, the wall thickness has NO performance advantage.

Secondly, do you have any idea what the wheelbase is and the overall rear width of the Stewart car? I was also paying close attention to the fact that it looks like Tony's car has very little front offset. I've got some ideas for an indoor car, but I think our largest problem is going to be that we only run Inline's so the CG's are going to be a bunch higher.
