I got the sub-belt harness bolts in on the passenger side today.

Great looking car schlicht911.

6 points? What are you going to do on the driver's side? I just got my seats and harnesses installed but still need to do the eye bolts at some point.

Marc Shaw

Yes, Schroth hybrids.

Same thing - I already got them installed and it only took a little DME relocation.

Drill the hole just big enough for the bolt and mount it with a huge reinforcing plate underneath. I tried using the 996 B-K sub bars but the angle was totally wrong so I had to drill the holes.

I was wondering why you didn't use the 996 sub bar? I used them on my car and worked perfectly. Actually the BK sub bar seemed to work better than the 996 bar.

I also used the 996 sub bars and everything fit fine.

Marc Shaw

Schroth specify that the sub belt must run 20 degrees backwards, no more and no less.

The only place to mount the B-K 996 bar was either at the front seat mount holes (way too far forwards) or at the rear seat mount holes (too far back). There is nothing to mount the bar to at the ideal location and, being handier with a Dremel than a welder, this seemed to work.

The only other option would have been to sandwich the sub-bar between the sliders and the side brackets but that would have required some extensive sub-bar mods to make it fit and then the sub-straps would be relying on the same mount bolts as the seat -- I'd rather spread the load out between different bolts. Safety is not a compromise.

If you have pictures of a successful mount that puts things in the right place, I'd love to see them as I could not make it work.

I see,

What seats are you using? The GT3 seats are set up for a perfect 20 degree angle with the sub bar, so it worked perfectly for me.

CWay27

Well Mark, that's how they are actually mounted. Not in sandwich but on top of seat side bracket. When mounted the bar aligns with sub hole in the seat. see picture below to show where the bar mounts.

cobalt

Correct,

The seat opening is actually slightly forward of were the bar is located making it a perfect set up.

Chris M.

Looking forward to the details in your write-up.
I was thinking maybe you didn't use the B-K bar because it's not a legal place for the subs in PCA club racing. Don't know about SCCA or POC.

Larry Herman

Hmmm. You guys are running the 996 sliders in your 964s. What else do you have to do besides bend the front tab back up into the rails?

Marc Shaw

Interesting - thanks for the photo.

The only difference I can see is that those do not look like the Recaro side mounts that I have and those do not look like the Recaro sliders that I have so I'm not sure that the way you have it set up would have worked for me. What type of side mounts and sliders are they?

I'll have to have another look at it tonight.

Marc

Those are 996 GT3 side mounts and sliders. They might not look like yours but 95% of side mounts, mount the same way and are all "L" shape. The universal side mounts have a couple of holes on the side to adjust seat height and bottom holes are usually sloted, to accomodate different sliders and also the wideness of the seat.

See picture below. the rear holes are slotted to adjust rake (front to rear) but the bottom holes (for sliders) are staight and not slotted.

cobalt

I used the BK side mounts and 996 sliders. Just bend the tab up and you are set to go. I needed the BK side mounts to lower the seat and angle it back but I am assuming the Recaro side mounts will do the same.

Marc Shaw

I bought the BK side mounts too but found the Recaro's let the seat sit lower and had more rake adjustment holes (5 versus 3, IIRC).

Cway: I am confused - the picture of the 996 GT3 side mounts do not look like the side mounts in your other picture?
