Ok so where are the proper safe locations to mount harness belts from? right now I have a Stable Energies B pillar harness guide bar and Memoryfab seats. What would be safe rear mounting location? I'm thinking the the upper C pillar hole from stock rear belt for one of the mounts. It places the belt above the guide bar. But where to put the other mount? The other bolt hole for the rear seat belt is all the way down. the belt would be like way too low.

where to put it? i'm thinkin about spot right at the rear of hump in the middle of the drive tunnel. put a nut and a sheet of plate on the underside of the tunnel. would that be ok? how do yall have the rears mounted?

 

 

You have a roll cage in there? I wouldn't use a harness with out one. The harness tends to keep you upright in your seat no matter what as they are designed to do. Even in a roll over accident.

 

well i have the schrothe rallye4 with the ASM loop. i'm only going for autoX's right now. when i get into road tracks and DE's, i'll def get a rollbar/cage

 

While I know the possibility of rolling the car during auto-X is small, it is still there. Not to mention the stiffness the cage will give the car is much better than being held in the seat a bit better. IMO.

 

oh i totally agree. it's just that a full cage wasn't planned in my budget till after I got some wheel time.

 

but...even if i had a roll cage, where would the harness rear mount be? or would u recommend using wraparound harnesses instead of bolt in's

 

Probably go with the wrap around in the case of a cage.

You might just want to use the stock seat belts and use the old flip lock trick with the inertia lock and the buckle.

 

If you're talking about the shoulder belts of the harness, then a good cage/roll bar with a lateral bar would be where you mount the harnesses in a wrap-around fashion. If you have just a harness GUIDE bar, the harnesses go over the harness bar and can anchor at the rear lapbelt anchors using Grade 8 eye bolts. The guide bar does just that -- it eliminates the angle from the seat to the anchor.

I'm just finishing up a 6 point harness install and will be using a guide bar and the rear lapbelt anchors. Yes, I know a roll bar would be safer, and a roll cage would be safer than that, and playing video games would be even safer. But it seems like a no brainer that harnesses are safer than DOT three point belts in just about any situation that might arise on track.

 

There was quite a discussion on this topic in the racing section.

To answer the question though, Greg has it right, the shoulder belts mount to the rear lapbelt mounting points. I'll have 6pt harnesses with a guide bar in my 944 this summer hopefully.

 

i'll take a pic tonite with the harness mounted at the lap belt points showing the declination angle.

 

greg? ritz? opinions?

 

Well, thats quite the angle. The harness bar I have makes an angle down towards the floor so the harnesses are at less of an angle.

I'd see what they have to say in the racing forum about that. I'm not sure if it's acceptable.

Heres a thread I made on the Ebay bar: https://rennlist.com/forums/showthre...ferrerid=56428

and this is a very good resource to read, incase you haven't already: http://www.schrothracing.com/docs/Co...structions.pdf

 

That angle is way too much.. most manufactures state anything above 30 degrees or below 5 degrees from the drivers shoulder is too much. Too low and the belts will cause the spine to compress in an impact. If too high, the belts do not provide enough forward restraint on the upper torso.

Also im fairly certain that bar is supposed to be used on the C-pillar for the 944. Its on the B-pillar for the other makes.

 

...hmm i'd have to check the part number. i know stable energies makes both a 944 B and C pillar bar.

i had my doubts. an alternative is to mount it at the trunk deck level. drill thru and put a backing plate on the underside.


ritz, can u measure the actual level of your bar in relation to the seat belt mounting hole? i want to compare how much lower your bar level is compared to mine.
