Cage or Roll Bar Specs?
I'm starting to do research for my cage/rollbar, and can't find any NHRA or IHRA rule books online.
I don't want to speculate on what quarter mile times my car will run, But it'll be mini-tubbed and have all the DSE goodies, along with smallblock and twin turbos.
Anyone know what wall thickness and diameter/points are required for different quarter mile times?
