installing harness

[andrew5826]

looking to install a 4pt harness for my brz for my stock seats if possible. can someone point me in the right direction to the parts i would need? and would installing a harness bar make the backseats completely useless?

thanks

same question here. Just do not want to delete the rear seats

You'll need either a harness that attaches to the rear seat anchors or a harness bar or a roll cage. In any of these cases, using the harness on a street driven car will be a terrible idea. If you use the harness on a track, go for it. Just be aware that with any of the options provided you have essentially lost the use of the (useless) rear seats.

Arnt some harnesses street legal for instance Takata?

Yeah Takata has their "drift II" series harnesses which are legal for street use.

Just because they're legal doesn't make it smrt.

Personally wouldn't do them on the stock seats. There aren't proper harness slots to keep the shoulder harness belts in properly. You'll also need a properly spaced harness bar or roll cage with harness bar attachment. Using the stock rear seat belt mounts put the belts at an improper angle.

Although I will admit harnesses do make for a cool looking part safety should be your utmost concern if your going to use it in the steer it track at high speed. For car shows, go right ahead.

Wouldnt it be safer considering its a 4 point harness therefore more points of contact? Plus Takata has the anti submarine feature too.

or are you talking in terms of an accident and you needing to be cut out. The rescuers are going to be like WTF.

Then again with a 4 point harness's buckle in the middle it may be easier to release if ever in an accident because itll be right in front of you rather than to one side.

These were exactly what I was looking to use. Show car though.

Only reason i wouldnt use them on the street is because of laziness lol the stock seat belts retract.

4 point, 5 point, whatever. Yes, I'm talking about in an accident, you will likely be worse off than if you had used your stock 3 point seat belt. It's a safety system that helps people stay alive in crashes, not just a safety belt.

Likewise, on a race car, they have a safety system which would include things like a roll cage, harness, helmet, HANS, etc. that would allow driver/co-driver to survive ridiculous-speed impacts/rollovers. To include one, but not the others on a street car would be akin to getting a knife without a handle.

I would generally not recommend running 4-points on the street. The way I understand it is that the factory 3-point belt will allow your upper body to bend over in the event of a roll over, where a 4-point will not allow that as easily. So with a harness, I would normally recommend a cage along with it to prevent the cabin from crushing during a roll over event. Now with any accident/safety discussion there is always a "well, what if this or that were to happen", and we could argue hypotheticals all day long, but for me personally, I will keep the factory 3 point for daily driving

Hope this helps.
Thanks,

OEM 3 point on the street or track
Aftermarket 5 point or 6 point with a roll cage on the track

Those are the only two ways I roll. If these are just for show, then add a harness bar and wrap the upper belts around it.

In the event of an accident, it wouldn't matter if it was 4 or 5-point, you'd still get seriously injured or worse if they weren't properly installed.

For harnesses to be DOT legal they need to have the ASM system. Which is a extra fold of harness length that is sewn into on of the straps. So in the event of a crash the thread splits and allows your body the extra movement it need so your body doesn't submarin, which could lead to more serious injuries. A cage wouldn't be a safe bet for a street driven car unless you wear a helmet every time you got in to drive. Imagine you get T-boned while in your caged car with not wearing a helmet. Now you have all these metal bars to split your melon on. I installed the Scrothe Rallye 3 harness in my frs, I barely use it, only when I go out for spirited driving or track days. But it's always there. And if you need to have rear passengers, it unbuckles easy and stores under the seat. Or cars have too short a rear seat section, so unless you have a cage or a harness bar(even more dangerous to have in a crash) then you need a 3 point that bolts to the upper rear pillar.
