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.

Gary, the John Elliott car's cage does extend the full width of the interior. Just because it is low up front, I don't think that there is a specific regulation against that. Bars extending into the doors was definitely not a requirement for Trans-Am cars at that time. Somebody who wanted to also run in Nascar Grand-American events or who just liked Nascar cage construction may have opted to do that but it was not required.

Awesome car. Here is a pair of magnesium TTDs that look pretty clean:

I don't like the way the main hoop leans so far forward. The front bars are too low also. It looked to me like a cage out of another car made to fit this one.
