My halo was done by Zero Motorsports and he tied my side bars directly under the halo so the cage wouldn't bend like the one pictured above. When I was out there, we discussed driver extractions and both of us agreed that if I'm that bad, cut the car up. They build chassis everyday so why risk trying to keep the cage on it. Safety comes first. The setup is on his Facebook page.

Considered adding a halo to our car, decided against it based on some of the reasons mentioned here.
Has anyone considered a window net above the drivers head?

That would be about as effective as a screen door on a submarine, IMHO! Bob

I would think the net wouldn't help much as it stretches with contact. It would have to be almost piano string tight to start with. It keep drivers in the car but not as great to keep stuff out.

Did I mention my hollow core egg crate flip top box. Imagine putting a a crush Prof box on top. A honey comb reinforced aluminum or carbon-fiber top 4 to 6 inches deep could sure eat up a lot of crash energy and help keep them pesky front bumpers from scratching up your custom hand painted helmet.

A net would be the best option to disperse the load and give complete coverage. Easy for extraction (knife) melt/burn away in fire, if you are concerned with its strength a sfi net would be as good as your belts.
Just like any other part of the cage/car if it bends and stretches it is absorbing and transferring energy.
A butt bar in a sprinter won't stop the rear-end but it does slow it down greatly.
(fyi great way to make nets tight is the soak them then install, will be tight when they dry)

I used that trick with my model airplane wings when I was a kid and I think the Indians used to use it on Cowboys also.

We have spent most of our time with a wing over our head when racing and I always called the wing my $500.00 crush proof box. I knew it was costing me $500.00 when the car flipped or got sideways with the roof facing traffic but it sure went a long way in preventing further damage to the car or driver. Money well spent> A very good investment for entry level racers.
