Bolt in frame connectors

According to @Mattax , to run auto cross class I am thinking of, they cant be welded in. Bolted in only.

Who made that rule up? A blind, deaf, dumb retard? Welded in connectors become part of the car. They make the car safer and stronger. You'd think they would want that on a bonifide race track. Even allowing welds in two locations really sucks, because that doesn't give the option of tying the floors in for a more factory installation, such as the US Car Tool connectors.
