Tubing thickness.

What is the thickness and size of roll cage tubing most people use that will pass NHRA tech?

Trying to order some tubing to make some things with.

depends on the actual bar of the cage (some can be smaller), but the main structure needs to be min wall of .083 (CM) or .118 (MS). A full cage needs min 1 5/8" OD and a bar needs min 1 3/4" OD.
