Please tell me you're using this in the context of a roll cage...

Not sure about the takata, but Schroth's street belts have an Anti-Submarine Mechanism (ASM) that allows the body to move like it would with an OEM 3-point. This allows the Schroth harnesses to meet DOT regulations and receive a NHTSA letter of approval.

I have the Schroth Rallye 3 and 4 harnesses installed in my cars. I really only use them for AutoX and RallyX; and use the stock 3-point for daly driving sicne the Schroth systems leave it in place. But I like knowing that if I have to run somewhere quick during an event I can use the harnesses on the street with full confidence.

That's not what I was referring to.

If anyone is even remotely considering a 4 point harness, one should consider getting it in the context of a roll cage.

Your head should not be the roll bar in a rollover situation when strapped in on a 4 point system.

At the track in the case of autocross, that's fine. But street use, please don't.

I would never ride in a car with a 4-point harness.

OEM 3-point or cage and 5 point. This is a hard and fast rule for me.

Stock 3-point or a 5-point with roll-cage as everyone is stating. Submarining is not something you want to happen. If you're just doing Auto-X, you can get something like CG Lock for the stock 3-point.

Not sure about the older models but the current Takatas use that system as well.

As others have said stock 3 point, or 5 point. That is if safety is in mind and not just looks.

You also NEED a harness bar to get the proper angle on the shoulder straps on a 4+ point harness.

mav1178 · 07-20-2013, 06:48 PM

ASM (Anti-Submarining) is not an issue when a car rolls over, and the roof (safely) collapses due to its design structure.

If you're strapped in to a 3 or 4 point harness that keeps your torso intact with little movement, your head is the roll structure.

The problem is not you, the driver... it's EVERYONE ELSE on the street. What's to guarantee a drunk driver NOT driving through a red light, broadsiding you, the car hitting a curb and you rolling over?

I used to be dumb and ran a 4 point harness with a stock seat. Then I saw a guy flip a car at the track and saw how little space he had, WITH a roll cage. No amount of aggressive driving + harness protection will protect you from the unknown, i.e. everyone/thing else on the road.

Edit: see this for a brief feeling of what your helmet will feel like when you roll. The guy's car (Legacy GT I think) rolled and the roof collapsed at the A-pillar as designed. He had no harness and see where his helmet sits on the roof liner at the end.

Save the money for something more useful, not a harness.
