Main hoop with 5 bends and no diagonal is likely going to be an issue for some groups. Was there a "To be such and such class legal" spec in your work order with the shop?
Might look at an X in the roof hole while you are in there.

yup, needs the main hoop diagonal
I'm really surprised by all the shops that build cages without reading the rulebooks or being familiar with the basic rules. Not just the guys who take their cars to circle track/offroad/dragrace fabricators but racing shops that specialize in Porsche's. Seems like every few weeks a proud owner shows off his cage only to be told it's illegal. Luckily it's a pretty easy fix in this case, but a hassle to have to paint it twice.

funny I ALWAYS see guys post pics of their cages here only to be told "something" is not right. my shop assured me all the rules where checked and observed and that is the cage I got. thank you guys for your inputs was hoping to get them.
going to the shop today for a little talk

wow looks great! Your going to have alot of fun with that car 
Might be a dumb question but why aren't the plates in the back of the car (by the rear seats) not fully welded to the body? 4th picture down where the cage meets the top of the rear wheel wells

Assurance is one thing, letter of the law is another. Your main hoop has 5 bends and no in plane diagonal. Based on the pictures you posted those are facts. as an example, a main hoop diagonal is specified for in print by some of the groups you have listed a desire to drive with.
A good and safe build, Passing tech and getting your log books in hand is the real assurance. It will be easy to read the rules of the groups you plan to run with on these two items. Not only is a main hoop diagonal called for but where the terminations are to be made is listed as well. Don't kill your builder unless he does not back the work to the point you have the log books in hand. No diagonal in the main hoop is a common cage/roll bar build fault.
Another possible nitpick Tech might have.
It could be just how they look in the pictures but the corner bends in the main and other tubes look very tight and have a saddle bender like deformation on the inside of each. The radiuses looks to be smaller/tighter than spec but again it could be the pictures. Too tight a bend causes the outer wall to weaken from over forming and thinning. You normally do not see any or only slight deformation on the inner wall. Radius to tube diameter is another in print spec and easy to check.

ok I did know that and they wanted the extra bend for fitment so the main hoop had to be a thicker tubing.

looking great any idea of Debut? If you are at PBOC Sebring in May swing by I'll have the usual fare going on. Likely already thought about it but you could always name your car: Arterial Motives
cheers.

Tom, You can make removable plexi inserts for the door frames. My doors weigh 5 lbs now. The EVO models have a frame included and fit pretty well. The plexi-glass can be secured from the inside for a little bit of security. Not sure what would be stolen, but you never know. Also get a fitted car cover and some straps for transport in bad weather or your start looking at a nice enclosed trailer!!!!
