Drag Racing Tech - Roll bar

Got kicked out of the track before I even ran 1 pass because apparently I need a roll bar...

I mean I'll be running mid 80s at the 1/8th...

But they still said I needed a helmet which I had

And they also said I needed a jacket...whatever

Anyways with my future upgrades, I'll need a roll bar regardless so I'm looking for a cheap one. Just wondering if fabing my own would be cheaper and how I would get it NhRA certified?

Buyimg one would be easier mwc i think has one wolffe does sorry for spelling

what is jig notched? and whats the highest et for 4 pt and 6 pt roll bars??

^^^^
nevermind. found out what it is.
