The MX/ATV brace, I don't see how will help much here as it doesn't prevent the head from going forward, only slightly limiting how forward can go. An automotive head restraint (HANs, Hybrid, etc.) significantly limits how much the head can go forward and tethers that movement to the body (couples the force absorption to the body).

Gotcha. I wouldn’t buy an ATV brace, just pointing out that a neck collar would likely accomplish the same result. I guess you could also teather your helmet to your seat too. I think the Hans is kind of a moot point with airbags though. I sat through a safety class one track weekend where they covered adding race harness, cage, race seat etc… negates the factory designed crash protection items. The factory seat is designed to break in certain crash situations, the airbags deploy with so much motion. Basically they said, if you install a race seat you should install a harness, roll cage, remove airbags, etc… or it would be less safe. Same with a harness. Etc.. they basically said if you do anything, you need to go all the way.
Not to derail the original post. I think a Hans is a great idea in a race car. I just wonder if that’s true with an airbag equipped vehicle with factory components. Maybe that’s why they don’t make more hybrids?
