On the surface, a driver harness seems so simple: Some webbing is strapped across the driver’s hips and chest and secured to the car. Once you start considering the forces at work, though, it gets complicated. HMS Motorsport, the U.S. distributor for Schroth harnesses, publishes a harness safety checklist and allowed us to share it with our readers. If every …

Don't do this. If you're gonna use a six-point harness, use it correctly. This guy even has holes in the seat to properly use his harness and save his testicles, but he choose not to. He bought a six point harness and turned it into a five point.

I went through this with Midlana. I received contradictory advice from belt manufacturer websites regarding recommended belt routing and angles, which was surprising since the physics is the same. Had to just go with the set of instructions that seemed to make the most sense.

As an SRF racer, that cover photo gave me a cold shiver.

Whats the deal with harness bars? Everyone I've heard says just get a rear hoop, as it comes with roll-over protection. Is there a use case for harness bars in autox or hpdes?

There is no use case for harness bars. So close to a proper roll bar in cost, installation and making the back seat unusable, but more dangerous than stock safety gear.

Its a case of all or nothing. If you are using a harness it should be part of a roll hoop (at a minimum) and you should also be wearing some kind of head and neck device.

If you're not doing that then as Tom mentioned the standard factory 3 point is the way to go.

Could you elaborate please? Should the camlock be just closer to the hole or is there something I'm missing that shows a way to split the two crotch straps before they go through the seat?

     If your track car is your daily driver, I'd like to offer a different view of a harness bar vs roll hoop. Most of the cars we tend to use are small and fitting a proper roll bar with enough clearance to drive the car without a helmet is a challenge. For instance, I put a Hard Dog roll hoop in my Miata and anything but the most minor collision would put me in danger of banging my melon on the padded rollbar. Even wioth the padding, that would be bad. I just got a Cayman, so I will only be driving the Miata to the local autocross and for local track days. I daily the Cayman and, although really nice harness bars are available,  the seats don't have shoulder harness ports, so I wear a Simpson Hybrid S in that car.

A proper harness bar, like a four-point hoop, allows the use of racing harnesses and HANS with a good racing seat, which is much more safe than a factory seat and 3-point belt. The better seat and harness will cut time off your laps right away, too. If the car has good rollover protection as built, a harness bar may be your answer. Most convertibles are another story, though.

My other cars all have proper roll cages, door bars, etc which are far superior to a harness bar or roll hoop, but just wanted to make the case for a harness bar in some situations.

I'm curious how a harness bar, with a proper seat, 5-6 pt harness and HANS is more dangerous than the factory seat and 3 point.

I have not seen any race seats with 2 holes for a 6 point with 2 crotch straps.
