Unfortunately, I have experience here, so highly recommend properly mounted ultrashield road race super seat. It might be called a new name now. Our own Redlineman turned me on to it a decade ago. It is custom made and is not a halo seat but a full containment seat. Yup there is a difference. Interestingly, one of my shunts ended with damage almost exactly like a friend just did except mine was a bit worse bending more of the car a bit further up. Both were rear offset impacts where seat support is very important. My friend, younger and tougher than myself had quite a headache but no other injury. Was it the difference in seats? Maybe. He had a typical FIA legal Sparco. Twice now, one being a rollover, my custom seat saved me with zero injury.

there was mention of height/belt angle issue with certain Halo seats. Can someone please elaborate on the issue?

^ wrong hole geometry and belt angle results in a downward vector on the shoulders which can cause a vertebral compression fracture

The Simpson/Safety Solutions Hybrid devices seem like a no brainer when HALO seats aren't an option. I almost never see them at the track, though. Am I missing something here?


Here's an video of a side hit that shows how much the head can move w/o any protection https://rennlist.com/forums/10509922-post2.html

Yep this is my biggest gripe with the SPG seats, why they didn't use the holes found on the SPG XL I don't know. But belt the angle is a little close to the minimum for comfort. Better now with my cage vs. the DAS I had previously at least.

I interesting thread

I have a halo seat and no center net, have been debating installing one, I probably will before Watkins Glen in sept

These don't help with driving to the track but the Kirkey seats have adjustable height halos in a full containment seat. (Seat shown without its seat cover)

That video kinda speaks to my question kicking off this thread. Yes his head moved, so did his body - which probably prevented a broken neck.

I'm not sure. Mine is the only one I've ever seen. I have the carbon one with quick releases. The appeal for me was mainly that it could work properly with more belts and seats -- it doesn't require the bump back that a HANS does because the device sits lower and clears the lower edge of the back of the helmet, so your head isn't pushed forward the way it is with a HANS in a non-HANS seat. It also is supposedly fine for both 2" and 3" shoulder harness, and obviously is designed to give some measure more side-load protection without a halo seat. As much as a true halo seat? Probably not.

I'm not endorsing it -- in fact, I do find it a bit cumbersome to use. My 3" shoulder harness tends to interfere with the dual tethers that connect to my helmet as I'm putting it on, and getting the bottom rings through the lap belt tabs while belting up without really being able to tilt my head down is tough. But I've learned to give myself a bit more time to belt in, and it's otherwise fine.

It's very quick to get out of the car with it, as well.

Paul, it may be that the Kirkey seat I mentioned earlier was that one, rather than one with removable wings.

In a race car I would only use a halo seat. We use a Recaro Pro Racer Hans. With it I see no purpose of a passenger side net. In a dual purpose car I would seriously consider the Simpsons Hybrid or a seat with removable wings.

Dr. Melvin, who does the research for Indycar, NASCAR, NHRA, F1, and many other series will tell you that your head can make it outside the halo. He has video of lots of incidents where the drivers head makes it outside the halo and is guided back in by the center net.

Matt do you have any links to these videos?

Can you expand on this, please? Were the incorrect halos placed too high or too low? What's the "correct" height for a halo? What about the correct/proper width (distance from helmet on each side)?

Btw, thanks for starting this thread.

Matt, I too would like to see these videos. I simply can not imagine how the head would escape from a halo and a strapped body only to be "saved" by a net so far away.
