Harness bar
 
Where would you guys mount a harness bar to? I know i'm going to use the stock seat belt bolts, but was considering running a vertical brace to the floor on either side of the center console. I know some will say "get a rollbar" But i don't feel i need one right now because i'm not doing any sort of racing or precarious stunts. But without my airbag i don't feel as safe/secure around the other dumbass drivers out on the streets.

a harness without a roll bar will not help your safety concerns, it only makes matters worse in case of a roll over...
even though i have a roll bar, i still use the factory cock pit brace for my harness
let me know if you need one, i have an extra

mazda/nissan 02-18-2008 10:45 AM

i'm not worried about rolling over, i'm worried about dumb fucks running into the back/front/side of me. And looking down at the steering wheel and imagining a stamped section in the shape of my face is not appealing

the stock brace works very well as a harness bar IMO, its very sturdy

mazda/nissan 02-18-2008 10:48 AM

what brace?

Oscar 02-18-2008 11:02 AM

the '94 and up seatbelt tower brace
good to know I can use it as a harness bar too :)

it connects the two seatbelt towers and its pretty thick and sturdy and runs just behind the seats exactly where you would want a harness bar to be...

ok.. just to clarify - driving with ANY kind of racing harness on street is way more dangerous then with 3-point seat belt. imagine that - you put a 4 point harness in and then drive your car into a wall at 40mph. guess what happens! yes, your entire body is moving forward and since harness doesnt stretch, your body will move underneath it and you WILL end up with some very very serious damage to your internals ;)

do NOT run racing harness on the street.

What about a 6pt??? Anti-sub belts

Loki047 02-18-2008 12:22 PM

wait why run them on the track then?

i personally run 4-point harness right now but only for one reason - to keep me in my seat on tight corners. i know for a fact that if i crash with this harness, i will most likely not survive (yes, im saving up for a proper race seat and 5-point harness)

3-point seatbelt will allow you to move your torso while race harness will keep you tight in your seat. think ;)

mazda/nissan 02-18-2008 01:01 PM

um 3 point harness has like a 3inch flap sewn together down in the bottom, how will this extra 3 inches save my life? Unless your talking about the upper part of the belt that rolls in the excess belt, that locks up under sudden deceleration. Can you explains some more?

Loki047 02-18-2008 01:21 PM

Those 3 inches are for impacts hard enough to release the airbags.

Urbansoot is wrong

1. If you want harnesses, you must have a rollbar first. There is no fucking discussion allowed on this point; that's simply the way it is. If you roll your car wearing a 4, 5, or 6-point racing harness, and you don't have a rollbar, you will die. There is no "MABYE" you'll die, there is no degree of dead, you'll just fucking buy the farm and that will be it. If you don't feel "secure" without your airbag, then put it back in.

2. whaamx5, shut the fuck up about the goddamn cockpit brace. It's bolted down with two bolts, and the harnesses pull in the wrong direction, which means those bolts will just bend. Bolts are strong in the direction they apply force, not perpendicular to that direction. THE OEM COCKPIT BRACE IS NOT SAFE FOR USE AS A HARNESS BAR.

4-point harnesses are unsafe. As UrbanSoot said, you'll just submarine and fuck yourself up. Get 5 or 6-point belts, or wear the stock 3-point belts. The only exception to this is the Schroth ASM system, which loosens one of the shoulder straps in the event of a collision, effectively turning the system into a 3-point system.

God, what a clusterfuck of safety advice this thread is.

Harness + Roll Bar = :D

Harness - Roll Bar = :(

Either reinstall the airbag to get the warm fuzzy or buy the full package. I run a 6pt on the street, but it's accompanied by a roll bar and race seat. My stock belts are in a box in my garage.

With a stock 3 point, you are physically able to move and get away during an accident. If the car rolls, you can duck. In the case of a driver's door impact, you can lean toward the pass seat. May not save you, but may prevent some injury or death. If your car rolls and you are in a harness and don't have a rollbar, your head becomes the roll bar.

ok i get why you think its not safe, but i have never seen an example of these bolts bent due to an accident, have you?? or are you just making shit up because you got sand in your vagina?
i mean, what you are saying makes sense, but those bolts look pretty beefy, i dont know if you have ever seen them or not, i just dont see them bending very easily...
