Using a harness with GTR Seats

[Jts-t]

Can a seatbelt harness be used with GTR seats without having any problems or safety concerns?

Thanks

I've seen it done quite a bit, but I don't know what safety issues there Are. I may try it with my own seats later on. Because stock gtr seats are comfy...

as far as i know my buddy has a 67 nova with racing seats and 4 point harnesses and unlett the harnett is attatched to some sort of cage its very unsafe as the harness could pull you down in the event of a crash. this is not reliable info but the way he explained it to me at the time made sence that you need some way to affix the top of the harness at shopulder height or higher like to a cadge. anyone with definite info out there though this is just from two guys bullsh*tn in the driveway.

If you don't have a cage, it's only for a ''cool-look'' factor.

I have a Sparco harness on right now. It feels really good to me.

Some pictures I just took









I'll have to mount it different when I get the cage in. Make sure you do a search to see what the safety specs are. I think the harness should be on a 45° and 90° if you have a roll cage. Iv been told if you mount the harness wrong it can break your back or crush your chest if there is an accident. I'm not fully sure about those specs, if someone knows please correct me.

Sorry about the pictures taken from cell. Didn't know they were so large.

Those pics are really helpful. That is exactly what i am looking at doing. I'm gonna look into it at some of my local shops here and i'll let you all know what I find out.

This should help a bithttp://www.pfadtracing.com/photos/sh....php?photo=282. As stated above, make sure your harness is mounted at no less than 45 degrees behind you.

This has been discussed many times, you should be able to find threads on this if you search a little.

It goes down to:

- You need a rollcage if you want to have a harness. If the car flips, and the roof gets crushed, the harness will hold you sitting up straight and you will get crushed.

- If you have a rollcage, you will need a helmet. G forces in an accident are pretty strong, and if you hit your head on your rollcage without a helmet, your skull will crack open.

- As for harness mounting, you will need a harness bar/support point to prevent the harness from crushing your spine down. Diagram posted by A18 is pretty good.

a harness isn't only for protection,
i use mine mostly for its restraining capability

you haven't done track yet, but believe me, when you go really fast around a corner and have to always hold the steering wheel super hard to keep yourself from flying out of the seat, it gets irritating after a while

ad to that my heavy weight, i get tired arms quickly enough

now with my harness on, super tight, i can't move an inch in my seat, and can concentrate 100% on just driving


just to make things clear, i don't use my harness on the streets, only on the track

but like some said on this thread, if it's not set properly, you can really hurt yourself. I knew everything you said, but whatever you do, I think safety first comes first. I'm no expert but your setup look legit. so you should be protected and fit tight in your seat.

well mine is setup correctly as seen in DarkCaporal's pic

but still isn't perfect since i don'T have a roll bar, in the event where the car flips and the roof caves down, you would have your neck snapped because you couldn't get out of the way...

so this winter i'm ordering a Cusco roll bar (half cage)

Exactly what Im doing! You mounted your harness in the same place I did. I too only use the 4 point for the track. Using it on the street can get annoying if you just going threw the city. Especially if you are making frequent stops.

my harness is indeed so tight, friday at our track day, i had to ask Tyler to close my door because i couldn't reach it lol

I thought the top of the harness had to be 10-45 degrees above your shoulder, not below like in that diagram.
