Jon,
In the rulebooks you posted today, there were some 'roll cage' requirements, and I thought one of them specified that the roll bar had to extend the full width of the driver compartment... and in the photograph posted, that one did not appear to do that? There were also requirements for certain size steel tubing inside the doors, connected into the roll cage. The RACE car went beyond the minimum, and had double tubes in the doors and additional reinforcement above the minimum. The owner/driver (Bob Christiansen) as an IBM mechanical engineering manager and a part time SCCA participant wanted to have the fun, but didn't want to pay too high a 'physical' price for his fun; I agreed with him, although the extra weight cost him in his finishing positions.
