R33 Harness And Cams Rules

[evil_weevil]

Hey guys,

For those with R33 gtst's, and harnessess - where have you bolted the shoulder straps to in the rear of the car?

I have used the bolt holes on the backseat from the back right hand seat, (where the existing seat belts would go if the backseat was there) however the angle of the harness is around 45 degrees...looking at the cams manual, it says the acceptable range is no more than 40 degrees...

So what have others done?

Is it enforced strongly also?

Pics would be handy if ya have them

Thanks guys,

Chris

Chris its rarely enforced strictly in a road car.

However one option is a purpose made bar that goes from tower to tower across the rear parcel shelf. I have made a fair few of them for R33's and they work fine.

I'll look into that!

Chris someone (and I can't for the life of me remember who) make a parcel shelf strut brace. If you can find out who makes them great or go with Brads idea. The rear seat belt points suck,,,in a roll-over your shoulders are subject to way to much force.

Just keep in mind cams rules are minimum requirements,,,always try to do better.

Cusco do parcel shelf bars for the R33 from memory.

There okay and you can wrap a harness around them, but not really strong enough in my opinion.

Ill try and dig up some photos of the last one I made but basicly it was 38mmOD 2.5 wall thickness CDS (same as minimum spec cage material) It had decent sized mounts and the harness mounts were the usual eyelets with welded in thread bosses.

Also did one for an RX7 not to long ago (actually you'd know the owner Chris, Craig Baker)

I think meridian motorsport in Victoria have them ready to go

What do people use in a R32?? I was going to get a bar made for between the towers like above but in the 32 this would also mean the removal of most of the front half of the parcel shelf.

Nah Brad It wasn't the Cusco one,,,I bought one off Johnny at UAS some years ago that was good quality steel that would do the job.

I actually gave it back to him thinking it was wrong. Strupid me.

Really the only way to secure the shoulder belts properly would have to be a half or full cage.

But after saying that the series 2 GTS-T's have mounting points for a strut brace in the boot which I use. Cutting the rear fire wall to run belts through there would be another way.

The Skylines parcel shelf is no way strong enough in my opinion,,,but the strut towers would be.

Hey Chris,

My harness is mounted in the back seat belt bolt holes also and i have roughly worked mine out to be 33 deg below horizontal or 57 if you are measuring from the vertical postion? When i fitted mine i never checked cams i followed the instalation guide that cam with mine ( it is a Takata harness ). I can post up pictures if you cant remember what it looks like or you are more than welcome to drop in on your way home on Sat and have a look.

I have attached the page out of the manual for you. Would mine pass?

I've seen them pass when they're at that angle, but it's not recommended. It's not worth the risk on your back in my opinion
