There are certain allowances for cars that actually ran GA, CF body panels, and stock fuel tanks instead of metal fuel cell cans. But as Cal Club's rules used to state one actually needed to have the GA log book as in the car can't just be prepared to GA standards, it has to actually be a GA car and started a race as such. It's still in the supp rules, but on the message board there's a note from the comp commitee that states the new rules, DOT tires and IT safety equiptment. I understand this came from pressure to run fuel cells as ITE is in the same run group as GT-1 GT-2 in our region. If this is what your supp's say you'll need to log book stating your car was actually a GA car, not a rule book saying the car was allowed as a GA car, sorry.
