Caged !

I think what they are trying to point out is that while all the OTHER safety gear is fine (no one has mentioned it being a bad idea) the cage is very obviously 3rd rate craftmanship. While a 'professional' shop may have done the work, roll cages and racing products are certainly NOT their cup o' tea. It's on par with having an engine building shop do your body work and paint. Professional shop, but not what they do.
Would have been better off going to a shop that builds dune buggies or rock crawlers IMO.

You cut and welded struts from a different car with different characteristics with no inner sleeve for extra strength at the weld joint as far as I can tell
You have a cage made of weld-seam tubing, designed by someone who doesn't do cages for a living, won't pass safety at any sanctioned event, in a very strange configuration
BUT you have awesomely expensive seats.... -

I would NOT drive that car, that cage is dangerous. You are brave.
here is an article explaining tube differences, http://www.xxxoffroad.com/index.php?…eral&Itemid=46
Here is an example of proper fitup
proper mig welds with good penetration, spacing and no visable welding defects(cracks or points of failure)
and a proper tig welded and gusseted cage (file too large to hotlink?)

Guess whoever made it didn't read the document very well
7.4.3.
ROLL CAGE MATERIAL
7.4.3.1.
Seamless SAE 1020 or 1025, etc. mild steel tubing (DOM) is the preferred material for Roll Cage construction.
ERW tubing is not permitted.Prius… because Pretentious wouldn't fit across the back of the car…
Cheap, Fast, Reliable - pick any two

For uncompetitive drift events, say in a parking lot, without tandem runs, they might let you get away without a roll cage… although these days with liability issues, that might be rare -

Guys, it's ok. The guy who built this appears to have looked at the pitchers of cages in that pdf. Who needs to read rules and regulations about basic material to use when you have PITCHERS! It's totally legit.

This cage should be fine for our drift events here. We only require door bars for tandem. Not sure what requirements he has.
ERW is fine from a safety standpoint. Our very dangerous-looking lemons car has it, and we pass the most stringent of inspections. Guess what? It's also MIG welded. DOM will probably be a requirement for new cars next year though.
Formula D cages have some pretty tarded requirements on the design.
Would I pay for this? No.
Will he be killed when his suspension fails? Probably not.sigpic
