I found a rear strut bar from cp racing. http://www.cpracing.ca/ it is a 4 point strut tower bar. they say it would work great for a harness bar. what do you all think?



thanks,

kevin

I thought to position your harnesses that low would not be too safe. I thought about that before with mine. Most recommend a roll bar or cage with a bar higher up around shoulder level. Having the harnesses mounted too low could cause your shoulders to be forced down instead of forward in a front collision. I don't know, they say its perfect.

I dunno I had them that low on my sandrail, I don't really know why it would be bad to have them that low, unless I am missing something.

It may compress your spine in a collision if their set too low.

the schroth rallye 4 harnesses sometimes mount to where the rear buckles are in some cars. and that is very low.

Just buy yourself a cheap ebay front brace and redrill the holes for the back and add some tube and form the bar higher, thats what i'm going to do soon. Of course if you can't weld then sorry.

i email them and they said it was designed for a harnesses

i own one of their strut bars (well actually the tripoint front and the rear)



i dont see how they can say the rear "is designed for" harnesses....it doesnt have a built in place for them...its just a bar with some other bars. nothing specially designed for anything...other then being a bar.



kevin.

It's a 4 point, looks like it's in there pertty solid. Usually other cars just use 1 bolt to hold their harness this would be like 6 or 8 or something. Is yours the 4 point? Or is it a 3 point bar? Does it really use holes that already exist?



kevin

you want the belts to be level or higher than your shoulders.... in a wreck... as your body puts pressure on the belts as you slam forward, the belts will have a downward pulling effect and crush your collarbones if they are mounted lower. Not something i would look forward to. Another thing i don't like about this bar is that it mounts FAR away from the seatback, which requires more seatbelt lenght. The longer the belt, the more movement you will get out of them. (think pendulum effect) If you're not gonna do a real rollbar or cage, i'd look at having a bar made that mounts to the TOP of the strut towers and atleast bring the belts up higher.



just my $0.02

If that is the case, then why does schroth make belts that attach to rear seats in some cars on the lower part of the seat, like where the buckle part is that you click your belt into?

because they are in the market to make money. I'm just telling you the way to do it that is the safest. Maybe you'll get lucky and never "need" them.

Here's a "quick fit" but they also make it where you bolt the eye under the seat where the belt itself bolts to.

Didn't you already make a thread asking for seat belts and mounting. I posted an explanation why you should do it the proper way instead of what your friends do.



Maybe you should learn to read carefully before asking the same questions twice.

The information being posted here isnt to inconveinence you its to help you from potentialy injusring yourself. The companys dont care however and are only out to get your money. Take the advice given mount them higher and do this the right way quit trying to find the easy way out.

I'm not trying to sound like a jerk or anything and i'm sorry if i am. But if it is bad to mount the harness low why does schroth make a harness that mounts low like in the picture i put up? they are dot approved, if it would highly injure somebody how did it pass?

My friends don't have rx-7's, they have VW's and the mounting point that is recommended actually works in their cars. I'm just getting frusterated because non of the schroth dealers, importer, or schroth themselves in germany know how to mount it in my car, but my car is on their reference list and shows it was tested and works.

I understand everyones points here. If you really want to know, I'd contact Schroth or the DOT or both. I don't see how that is safe, period. Its not rocket science. When its mounted that low, it will pull down on your body instead of just forward. With that much force on our bodies, somethings going to break and most likely it wont be the belt or seat.



It may work as a mounting point in their car but what are the results of a crash? I know what you mean, I had a friend who installed one the same way in his Acura... the belt on a 45 degree angle straight down to the rear seatbelt mount point.

just because a company makes something doesnt mean it works like its intended to...and DOT approval on seat belts probably has more to do with the strength of the belt rather then its mounting locations, i would think.



As for "why do they make ones that mount there"



because they know dumb kids with hondas who want the "race" look without the race car will buy them to look cool...thats there intended purpose when being mounted like that.



I doubt that would pass tech inspection at a dragstrip...ill have to take a peek at the rule book later, but if i recall corectly there's a specific measurement for where the mounts must be attached etc, one of which i think is the height of it relative to the seat.



again i could be wrong but i swore i saw something about it in the handbook.



kevin.

This may sound crazy, but I would follow the same guidelines that I do for my child's safety seat. Same concept, it's a 5-point harness. They say to never have the should belts lower than the shoulders, they must be even or above the shoulders. I would think child seat manufacturers would have to follow much more stringent guidelines than the racing harness guys.

pw3nt.





while we're on the topic of cpracing, I'm interested in their 4 point roll cage, any opinions on that?

where it bolts (on the piece in the floor behind the front seats that is like a "mini wall" for the storage bins) isnt exactly the best place, IMHO, to mount it. Seems more likely that that area would collapse in an accident...and i dont think moutnign ti there is NHRA approved either.



of course if you just want the look its fine.



and again, this is my understanding, i could be wrong.



kevin.

anyone know where i can get a cheaper rear strut tower bar that i can modify to make it higher to properly hold the seat belts? I used to see ones on ebay but i haven't seen them in a while.

One picture i found of harness mounting in Rally cars..

Only diff for mountingpoints in Drag racing is as far as i know that the shoulder belts cant be more than 4" lower than youre shoulders.



Plz correct me if im wrong.

my 0.02 cents, i wouldn't attach harnesses to a rear strut bar, if you're going to run with a harness best way to do it is with a cage i.m.h.o.

I don't want to have to modify my car with a cage, bar or anything. so i'm going to return it and get a momo seat.
