OK, I will try to clear up the roll bar issue. I have built & homologated many cars with the SCCA. Roll bars must have forward facing roll bar braces of a minimum tube diameter of 1.0" x .083" wall DOM steel tubing. However, if you want to have an alternative design approved that is possible. You must supply a load & stress analysis of the alternative roll bar design completed & signed by licensed PE (Professional Engineer). The specifications for the required loads is in the GCR. There are many cars that have alternative designs such as all the Van Diemen formula cars as well as most Atlantic car. I have personally not seen (at National races) any F500s with alternative designs.
Call John Bauer at the SCCA to discuss this in further detail if necessary. Thanks ...

John, I haven't looked at the GCR recently, but I think the reason you can't find a definitive statement is because they don't care. As long as you have a brace no more than 6" down from the top of the roll bar with gausset. The bracing in the cockpit area is to stiffen up the chassis in that area. The Master Kill switch should be located on the right side of the car facing out and just behind the main roll hoop.
