If its not in the rule book then I would guess not. However...when they inspect the car they could still gig it if it had a bunch of sloppy looking , unsafe looking weldswelds. As long as the weld are good and look good...I think you will be OK.

No, they are mainly checking for tube thickness and placement.

The BEST thing you can do is call your local track(or NHRA.com- in your division), and see who the NHRA inspector is for your area. Give them a call for what THEY are looking for.
I've seen certified cages that our local guy won't pass.

Big thing here is EVERY joint has to be WELDED FULL PERIMETER.

NO grinding of welds. Period. They would rather see a catapillar of a weld (Cold) than any grind marks on a hot joint. (Hard to believe, but true)

All tubing thickness better be to spec, or it fails.

Mig for Mild Steel (Tig is acceptable, but Mig is preferred) , Tig for Moly. NO STICK WELD.


Your BEST BET is to buy a kit from a recognized manufacturer like Alston, Quartermax, S&W, etc. Do yourself a HUGE favor and get a "Pipemaster" for doing your joints. Best $50 you'll EVER spend.
