you think after welding in it would pass inspection for like A class shit.???

Typically, most, if not all sanctioning motorsports organizations require a minimum of 1.75"OD tubing to be used for the main structure (main hoop, halo, A-pillar members, door bars, rear members, etc.) of a roll cage. Then the tubing wall thickness is determined by the race weight of the car. Usually racecars that are 3000+ lbs require 0.120"+ and sub 3000 lbs can get away with 0.90". Then there's always the debate of ERW (Electric Resistance Welded) tubing and DOM (Drawn Over Mandrel). So it's a little more complicated than just being "weld-in" or "bolt-in." If you are interested in competing in any sort of sanctioned competition it'll be very wise to review the safety regulations!

So with that said, yes, don't expect to install ths and run a SCCA/NASA race. It does have a nice thick wall though and will fit with an interior still intact, which is cool for a weld-in cage. Also, it's very inexpensive for a cage!

I also want to add that just because this cage wouldn't pass professional sanctioned motorsports tech inspections doesn't mean you wouldn't be safer if you had this in your car versus not having anything at all (obviously installed and welded professionally) if you just attend regular track days (HPDE's) or other non-competitive high performance events. This cage plus a 5 or 6 point harness would definitely be safer than nothing and your everyday 3 point seat belt.
