i have a question about mounting my harness in my EH3. i ordered a Schroth rallye 3 harness and this website http://www.soloracer.com/harnschrothfaq.html shows that i should mount it to the C-pillar.

here come my delema. i am currently in the process of building a cage for my car and i have been toying with the idea of putting a harness bar on it as well. would it be better to make a harness bar and run the harness over that down to the floor (back seat mounting point) or should i just leave the harness bar out and run it to the C-pillar bar.

 

please don't reply unless you know what your talking about

 

do a search for "harness" on this forum,you'll find all the info you need.
summary:
people don't like the harness you have.if you want a harness,get a real deal 5 or 6 point setup.your harness has no anti-submarine belt,and the shoulder belts mounting so far out on the lap belt can lead to further injury since they put a lot of pressure on your shoulders,and none on your torso.

you need to keep the shoulder harness mounting belt(s) as short as possible.preferably tied to the B-pillar area.the more harness length,the more it stretches,possibly allowing you to move too much.

some will argue that if you have a harness,you need a bucket seat.
some will also argue that if you have a harness,you need a bucket seat and rollbar.

best option is a harness bar on the B pillar,with the harness tied to it.be very careful of a C-pillar bar-they're usually just JDMish flimsy crap that are in no way meant to support a harness.the only kind of crossbar you should mount a harness to is one built specifically for that purpose.

Mounting the harness that far back is never a good idea.

A good question for you is: What will the harness be used for primarly?
Only thing I would suggest using it for is AutoX and keeping you planted in the seat a little better.

I would not want to wear something like that at a track day or on the street!

 

auto-X, and the occasional test and tunes

 

Whatever you do, do NOT use a C-pillar bar as a harness bar.

 

that was never even an idea

Schroth's Rallye 3 and Rallye 4 line up of harness do have an anti-submarining device. You should do your research before you just assume they don't have an anti-sub strap. check it out for yourself. also, when wearing 3 or 4 pt harnesses, make sure you REALLY tighten the lap belt because that belt will help keep the belts from moving upward and into your stomach.

anyways, the best option is to have the harness wrapped on a harness bar directly behind your seat. since you are making a roll cage, that shouldn't be a problem.

 

the only time ive seen a harness mounted that way(in the photo) was in older VW cars during autox. i personally have a harness car built into my roll bar. i think if you dont wanna go that car that a harness bar is the best bet.

i looked at the diagram the OP posted.it's clearly titled as "Rallye 3",which is the same belt he says he has.the belt pictured has no anti-sub belt,and appears to be a single buckle,"street" type harness.
i just "did my research".....



no anti-sub belts there.i know it has "Scroth's unique ASM system",but i don't see anything other than the typical ricer belt.
shoulder harnesses connect to the lap belt way too far apart.puts a lot of stress on the shoulders,doesn't put any on the torso.makes it easier to squeeze between them in a crash,and come unsecured.

i had this harness in my car years ago.no matter how it was adjusted,it was easy to pull the lap belt way too high.it was installed properly,it's just not a good solution.i got a REAL harness,now i'm fine.


so.......i did do my research.

Here's a video showing how the ASM works:

Schroth makes some nice harnesses. There's a reason why half of the Nascar/Nextel cup drivers use German harnesses rather than 'Merican.

From your first post:

...

As for the 4-point, Schroth knows what it's doing. If you're going to use a 4-point, that's the one to go with for sure.

 

Mebbe when he said:

Great video!!!! Thanks for the post

sounds like it might be best to mount it to the c-piller like they for the ASM to work properly

i'm not doubting the quality of Scroth products.i'm saying this design-along with other "sport" harnesses like it,including ones made by other top brand companies like Sparco-just aren't a good idea.
when i had this harness in my car,i never got to head-on crash test it(not that i wanted to).i did have a glancing blow off a tree,but it was a side hit while spinning,so the harness i used didn't affect it much.
my point is if you want a harness,get a real one,with a real anti-sub belt(s).

i'm sorry,but i don't see any amazing technological breakthroughs in that video,or by looking at the harness.sounds to me like fancy-talk that's basically saying "the shoulder belts let your upper torso move forward more so that you wrap around the lap belt,keeping you from sliding under it.that's a lot of force on your abdomen,and the amount of upper body movement that harness allows could easily allow steering wheel contact in a small car(wasn't that a problem in that Suby where the guy wrecked at a DE?).
Honda spent a LOT of money to perfect their stock seat belts.i just feel that if you're not going all out,then keep it stock.
you really need a bucket seat,get a 5/6 point harness,and at minimum,a B-pillar harness bar to attach it to.

does the lap belt bolt to there the seat mounts to the floor, or onto the seat itself?

on a stock seat,use the two stock lap belt mounts.
Chris

 

i have del sol seats but i would assume it's the same since it's a stock seat also, thanks man

 

well i put it in today, i just put it on the C-pillar bar for now, monday in class i might figure out a way to mount it to the harness bar.

 

The 5th point helps alot so the harness doesn't ride up your chest when tightening it down. The ones with a 5th ;point of course...
I have my harness strapped to the rear strut tower brace which is beafed up and made from steel as opposed to aluminium. Not the safest route but I will soon be putting in a roll bar system so that will be corrected for good soon.
If the C pillar bar is aluminium I wouldn't count on that in any way to save you.

 

it is mounted to the same hole that the stock rear belts bolt to on the C-pillar.

 

I don't get it, you have a bar in the car with a spot for a real harness and you went with this inferior piece?

5 points properly mounted are sooo much safer than the belt setup you have in your car now.

 

it is mounted how schroth recommends it be mounted, what don't you get. i will most likely be mounting it to the harness bar tomorrow anyway.
