My cage builder had a question and we wanted to make sure we have no complications down the road. The car will run in G & H mainly, but I want the ability to run F also. We are building the cage out of 1 5/8" and he wanted to know if every single bar has to be 1 5/8" or is it just the main hoop, bars that run to and down the A pillar, etc? Can the door bars, the seat bar, dash bar, rear bars, etc be 1 1/2"? Or do we have to run 1 5/8" for everything?
Also he was wondering if there is an SFI spec or other spec, that we can build to and not worry about tech? Example: Follow x.x spec and add the gussets, floor plates, ect from the rule book and you should be good to go. He has read through both rule books I have and and was a little concerned about specifics on bar placement, ect.
Thanks,
Mark
