Unibody car.
I plan on running this car at multiple venues, to include road racing. The floor is rusty as h, e, and a couple of hockey sticks, the roadracing org (24 hours of Lemons) requires a fairly traditional 6 point cage. I see other /Pro or /Alt cars with a significant foot protection section added to the cage. The rule book is unclear, showing a 4 point cage as adequate... what am I missing?
