Topic: Cage sheet metal question.

What thickness of sheet metal is acceptable to set the cage on? I have 1/4" plate but that seems to be a little overkill

Re: Cage sheet metal question.

3.E.1.a Rollbar Tubing and Spreader-Plate Specs. Minimum tubing size for cars weighing under 3000 pounds as raced is 1.50″ x .120″ or 1.75″ x .095″. Cars weighing over 3000 pounds as raced must use a minimum tubing size of 1.75″ x.120″. Properly bent, racecar-grade and -quality tubing is mandatory: no stretched or crushed bends allowed. DOM mild steel is very strongly recommended over ERW (seamed) tubing.  All spreader plates must be mild steel, at least 24 square inches, and at least .125” thick.
