In the event of a roll-over collision, a harness bar, especially with HANS, will pretty much guarantee that your spine is crushed by the weight of the car as the roof collapses on top of you.

The 3 pt belts allow you to move yourself out of the way, or for the roof to move you out of the way, in the event that the car gets suddenly shorter. A real harness will hold you firmly in place while you're forcibly shortened by 3000 pounds of awesome.

IF the roof collapses on you. I've seen plenty of rollovers that didn't crush the roof.

The structual design of our cars are pretty stout. I think it more so if you were to roll mulitple times is where it would come in to play. For each roll the structure will weaken.

Driving a street car on the track is always going to force compromise in safety. You're not going to be able to run all safety equipment a true track car can. You are circumventing many of safety designs street car has had engineered by factory when you start putting harnesses anspd race seats in a car. Safest cars are street cars with all safety systems intact on the street and full on race cars on the track.

For me I went with race seats, rear rollbar, airbag delete, schroth harnesses with neck brace and arm restraints. Is it perfect? nope. Could I be injured in serious mishap yep. It's personal choice. For me it was best compromise. I have some rollover protection, good race seats provide protection as well. My roll bar is 4 point system that is very solid. But let's say I go front half of roof into cement wall? I won't be a happy camper. Would be depending on hoop just behind my head to keep roof from crushing.

I'm getting HANS device for my setup.
