modifing factory seat rails

[psychofox]

If you're planning on doing a side mount seat, if you mount the side mount rails on top of steel between each of the rails (as proposed above) you won't get a very low seat position!!! the seat must sit between the rails to have a chance of being low enough.

There is nowhere you can put harnesses form the factory at the back. make up a bit of pipe that goes between the top seat mounts and mount the harnesses to that.

or buy an A-Spec brace

ask steve for one.

behind the back seat in the floor there is a child restraint attachment points, one on each side of the car.

I plan to use these.

I wouldnt rely on one of those rear seat mount braces, its only thin sheet metal with a couple of spot welds for mounting points.
Especially with 2 harnesess fitted!

I dont think those braces make any difference appart from added weight.

yea i was planing to use these as well but the eye bolts that i got with the harneses have a larger thread diameter than the child restraint ones. unless i make a plate or see if i can buy a high tensol eye bolt to fit into the hole. will most likely make a bar across the back. a nice sturdy one.

Don't mount the top two harness straps that low. They should be as horizontal as possible, otherwise in an accident they can pull your shoulders down and really mess you up. The CAMS manual has good guidance on how they should be fitted.

And the seat latching points look reasonably sturdy to me, everything in a car body is just thin welded sheet steel.

who can make me a bar to go across the back seat for my haneses on the gold coast?

Strongly disagree on this one, I've had these braces in my last 2 sprinters and they make a pretty good difference. Especially when you have stiff suspension and bushes in the rear.
They made a shite load more difference than the rear strut brace that I had...

[biggo]

what he said, you kidding your self if you think they dont do anything

i have personally noted (and heard ) the difference

im too tall lol i had to make custom fixed position seat mounts just so my head could clear the damn roof lol but for the harnesses mine were EASY autotech 4pt: the lap belts use the same 14mm bolts so that was a breeze and where the back seats used to be theres a boxy lookin piece of car frame that used to support the front of the back seats. there was a hole in mine that was perfectly aligned with my steering column so i just bolted the 2 shoulder straps through that hole (esentially making it a 3pt) it works great and when i want i can still throw tha back seats in n the harnesses dont get in the way... well not as much as they would if you had them bolted to a reat strut brace...

So I guess your shoulder straps between your shoulders and the mounting point are almost vertical. That is bad. If you ever take a hard hit with a harness like this you can do some serious damage to yourself and the harness wont work as effectively.

The shoulder straps should be horizontal. Attaching them to a rear strut bar is about the best you can do in a hatchback.
