No offense to Troy, but if that bar were simply for decoration, he'd be fine. No sanctioning body would accept it. Why? Well, mainly because it allows the door bar to elongate as opposed to staying put under stress. That bar, when the cage is hit from any direction except down from the rear, will be under tension..not compression. That bend gives the bar more linear distance before it has to pull apart. Meaning, the cage's main hoop can be pushed back in a forward hit, or the bar can intrude the driver's (or passenger's) sapce in a side impact. Drag cars can get away with little worry about side impact, hence the swing out bars. A road car, or a fast street car MUSt deal with side impacts. Think of sliding thru a corner and hitting sand, the car swings off teh shoudler and catches a tree on teh drivers fender/door while moving at a 45° angle to the tree. That bar will bend trhu your legs, possibly into your side thru your arm. It's a bad design, born of "pretty", not safe. The swing out bars are not as good. But I would rather seet you with no halo or door bars, than those low bars. It's up to you. But the mild SCCA cars only need a 4 pt roll bar to guard against roll overs. Also, I would not tie the cage into the crossmember for the air bags. Personally, air bags belong on show cars and dump trucks. Not high performance cars. But the rear bars need to go to the back of the car. Not the front of the trunk.
