Does anyone know the rules for weather or not the floorboard below the seat can be modified so that the seat can be placed lower in the car? I am asking specifically for SCCA production rules but would also like to know for other organizations. The reason I ask is that my head is real close to the roof of the car and I already have the seat bolted to the floor and firewall so it can not be placed lower without modification. I have passed all the safety inspections but I still don’t like it. The seat is an Ultra shield Aluminum one and it is 20 deg layback (the most if I am not mistaken on this seat)
Thanks,
Rob
