If you're gonna weld, get a roll bar and add safety. If you just want a harness bar, go with a bolt-in.

Rigidity is a funny word when talking about 944s. They're pretty flexy.


PS: Maybe I'm misinterpreting what I am reading, but every harness bar I've seen mounts at the "B" pillar which is where the the FRONT seat shoulder harnesses mount, not the rear.

And the below picture shows the harnesses anchored at the harness bar. If at all possible, they should lap OVER the harness bar and get anchored at a better location (like the rear seat belt anchor points).

I'm confused about that. Wouldn't anchoring the harness below the bar actually give the harness a mechanical advantage over attaching it directly to the bar, making it MORE likely to fail? I suppose even if it did, you would still be at least strapped in, but probably not very tight, depending on the routing.

Do you guys actually use your weltmeister bar for harnesses? I have one and I wouldn't trust that thing for more than a camera mount (which is what I use it for), so I ended up buying one of the redline ones as well.

The weltmiester bar mounts between the two rear shoulder belt bolt holes, so it is on the c pillar facing forward. The brackets and everything are angled in a way so that the bar won't move if any tension from the belts is put on it. I may have some pictures when its installed...

First off, in a 944, the harness bar mounts to where the rear seat belt shoulder attachments are - not the driver's shoulder belt attachments. The harness bar will be approximately above and a little in front of the rear seat back (usually preventing your from folding your rear seat down).

Second, using harnesses and NOT using a seat that's DESIGNED for harnesses (i.e. with the proper pass-through cutouts) is a BAD idea - and in fact, not acceptable at PCA events.

If it's the original poster's intent to cheap out and weld some old piece of pipe into the car to save on cost - and he's not willing to spend the money to buy proper seats - then this obviously is a foolish enterprise and should be abandoned immediately.

Just my 2 cents.

Here are some (crappy) pictures I took of mine with my camera mount on it. In the one that shows the mounting plate, that plate with all the holes drilled in it is not part of the bar - I added that in an attempt to prevent leaving marks from the bar on the interior panels (it didn't work and looked stupid), but you can still see how the bar itself mounts to the shoulder belt holes.

Here's an older picture of mine just after installing it, prior to wrapping the belts through.

Yes.
So you use the Redline bar AND the Weltmeister?

So I used those and they worked fine. The bar fits perfectly in that area, and I couldnt get it to fit down lower where the seat belts normally are. I'll see if I can find a picture of mine...
Yes, mine are connected to that same spot. I thought they were there for the (option) of full shoulder rear seat belts. I could be wrong though, The bar for me ALMOST fit, the end peices were just a tad too short to get the bolt to grab, I didn't want to bend those end pieces, so I just bought slightly larger bolts.

Here is the only picture I have of it:

Van-
I was thinking of having a local shop do a single rear hoop with supports going into the trunk area with a cross bar for a harness to grab onto.
I was just seeing what the safest and easier way of going about this would be.

There is a local company here in Orlando that sells roll-bars for $380 if you want to go that route.

Tyler,
I never realized those holes were for optional rear shoulder belts!! Thats interesting! I've worked at a Porsche tech shop a few years ago and never saw a 944 with rear shoulder belts, they must have been a very rare option! My Welteister bar fit perfectly in place though.

+1 on a bolt in roll bar. Might be the easiest solution.
