Thanks for the input the harnesses are just for show im getting 5pt cam locks for other stuff. I do have kids but they are no where near the bar i had them in the back already. As for the bar like i mentioned in the post it was just a test fitting.

They may not be close now but wait until you brake suddenly and they all get a harness bar to the face. Poor kids

The harnesses are one thing, but the fact that they're mounted to a mouse trap, makes them completely useless.

Even if your kids are strapped in the back, god forbid if you have a head on collision, the seat belt stretch. This slowly brings the body to a stop, and the soft backside of the front seats help.

Take the bar off it's rice that ruins an otherwise nice protege.

agreed, lose all of it and use your factory belts. if you want race car harness belts, get a race car. don't play with fire, especially with kids. why risk getting them hurt because you want to be "cool".

[speedracr79]

Well the bar is staying and i dont see how its rice and will be useless mounted where it is. I guess Sparco is rice for their bars,as for the mounting the factory belts are mounted in the exact same spot as the stock belts.
heres a pic of sparcos bar mounted in the exact same spot as mine so i guess they got it wrong too.

Who said i wanted to be "cool" I know i never did. As for my kids are conscerned i appreciate all the worrying for them but they will be just fine. When i said i had them in the back already, my cars on jackstands in my garage and has been for about a year. i had them in the back and had them sit foward and see if they are in range of the bar and they are not.

I know people who have run harness bars and harnesses with kids and people in the back and not one has had their head smashed into the bar, like i said before im not gonna have any adults in the back anyways, so thats enough about that.

So if i want harnesses i have to get a race car how do you figure. So if people want fast cars they should get super cars and not make their faster?

For those who dont agree with my choices, or have a problem with the parts i install, thats perfectly fine, you dont have to. But this is my build and i will build it the way i want. When you buy my parts for my build, or fund it in any way then you can have a say in how its modded.

For those who unsubscribe for my choices i understand its your choice.

Again i appreciate all the worry but the bars gonna stay, my kids are gonna be fine and if we could get back on topic id appreciate it.

if you ever read d-sport or scc you see these bars all the time so your not the only one running this. no idea if it will actually improve much but def looks cool if you can make it work safely.

i *almost* made one as I always thought they looked cool but could not justify having harness' in my DD. I hate anyone who asks to ride in the back anyways so them getting new teeth is cool with me. the biggest drawback would be not being able to bone a chick on the front seat if the bar does not let the seat recline.

by posting your build on the internet, you've simultaneously asked for people to comment about it. that's basically the idea behind a forum.

but on topic to the bar, sparco is a company in the business to make money. take that for what it's worth.
Also for what it's worth sparco doesn't list a bar for the protege so you posting links is moot.
to prove that here's a link to a person with no teeth. same concept
http://haquelebac.files.wordpress.co...00&h=323&h=323 moot.


the reason for my critique is because of where the harness bar bolts on to.

That point is super strong no doubt. the stock belt attaches there.
However in a crash when your body applies force to that point via the belts, the belts pull that point downwards.

In a severe crash the sliding mechanism will fail, causing the mount to bottom out, which is ok as it can't go anywhere past that.
If you figure from the top point to the bottom is 6 inches. which translates to less than 3in of forward movement. (even less so since it's at an angle to your body's movement)

the way you have your bar mounted has the sliding mechanism at the very bottom.

All good and great right? I just said it won't go anywhere else from there right?

no.

in a crash your body will apply tension on the belts.
the tension from your belts will pull the bar forward which can't go forward.
the harness bar, the ties to the floor, and the chasis create a triangle.
If the sliding mech fails the harness bar will move up. simple geometry. as the harness bar moves up, the harness goes slack.

now, looking at your pictures, the angles in the said triangle are very small where the bar meets the chasis, as those get closer to 0 (bar and supports are perpendicular to the floor) the harness bar is completely ineffective.
this is where my "trap" comments come in.

If you insist on this bar. idealy, you want as much angle between the bar and the support rod. the best would be if the support rod is 45* to the floor.


Here you see if the bar moves up, even if the point where the bpillar is warped due to a roll, the simple angles will not allow the bar to move forward by much.

this to me is more ideal, as the supports also go into tension in a collision.


how the belt should be mounted

[speedracr79]

I know its the internet and people are gonna comment and talk smack or give props, im fine either way, but from what ive seen from this forum you guys seem to be pretty cool here so i dont have to worry about the smack talking here.

Well like i said i have no problem with comments and critiques at all, they are welcome especially if they are like this one with some helpful info not just remove it or people will smash their faces in it.

As for the pic of sparco i posted it for the mounting points as a referrence so the point was not moot. I never said there was one for a protege so i dont see what that has to do with the pic being valid or not as a referrence. Thanks for the funny pic though.

As for the bar i will take your info into advisement and i will make a final decision thanks for the input

Unless you are installing harnesses for the rear passengers, they will move in the event of a collision.
