I've owned four Mk1 996 GT3's, one of which was a Clubsport, all had bucket seats, I also owned a 996 GT3 RS and a 996 GT2, both of which were fitted with bucket seats from the factory. None of them had the seat belt receptacle "threaded through" the seat shell.
I crashed one of the GT3's heavily into a tree at speed, side on. The seat belt retained me perfectly, (some may say too perfectly, as I fractured a couple of ribs where they impacted on the seat shell).
If the factory don't see fit to thread the receptacle through the seat, and I elect to be a crash test dummy, I call BS on this "theory" mainly perpetuated by folk on here. That's not aimed at you BTW

This was the result of what I estimate to be a 70mph off road excursion (backwards) in the dark :







This is the bulkhead between the engine and the cabin, and it's the other side of the car from the point of impact. Those spot welds have been ripped apart and the bulkhead deformed to the point the engine was trapped between the chassis legs. That should give some idea of the forces involved in such an accident, and why I don't buy into the seat belt receptacle "myth". Had a suffered some kind of injury/trauma to my hips or pelvis, I might concur with this nonsense, but I didn't, so I don't.

So how was it run? I’m confused now.

holy moly. glad you are still with us.

I have run my receptacle through and outside the seat. I understand why through the seat would have a benefit but currently keep it outside. I may be a bit thick, as it were, and the belt is relatively close across my hips.

on a side note, not sure why you get to have four gt3s and I don't get one. such is the nature of things.

Glenn, Don't be jerk as he is letting you know your driving things are potentially unsafe.. I would think that has value to you and your life.. Also he is correct about making sure you or anyone doesn't share unsafe info.. Take the feedback and adjust accordingly with correcting it..

GC996

Unfortunately, he is wrong on this one. But appreciate his efforts.

Justin some people will just never back down. The OP asked a question about 3 point belts with GT3 seats. I provided the factory parts diagram showing the correct routing and provided part numbers to accomplish this. The OP thanked me.

I also had an experience with a PCA instructor taking a ride in his car that had 3 and 6 point belts. Since I didn't have posts on my helmet for a hans device he removed the lap belts and routed the receptacles through the holes. This is all the information I have or have found. I'm relatively sure that for a regular sized american either way would be safe. A very small person or a child, you will never convince me that through the hole is not safer.

From a post about this subject.

GC996

A couple of points.

1. No way would i consider feeding the seat belt thru the right hip hole on the street or track. The reason is that in an accident, you want not only protection during the accident, but you also want to be able to get out of the car quickly. Last thing you want is to not be able to get it out of the hole.

2. I applaud the idea of using a 997 part as a potential improvement to a 996 GT3 seat set up. However, you will need a much longer strap than the 997 strap to not only make it comfortable but also to work with a waist belt from a racing harness. If you have both fitting thru the right side hip hole, the seat belt strap will need to be plenty long to fold it out of the way so you can use the harness waist belt. As you can see from the pictures, it's very tight.

3. As been suggested by many of us in this thread, porsche and recarro both have not come up with any suggestions beyond running the oem seat belt over the right side of the 996 GT3 seat and plugging it into the connector. Hence why it's what has historically been done.

But as I said many times, if this is an issue, the 996 GT3 seat owner may have the wrong seat.

This was my Mk1 Clubsport :



All my other GT cars equipped with factory fitted buckets seats (But NOT 6 point harnesses) had the receptacle outside the shell too. If you want to be properly restrained (ie on trackdays) fit a sub bar, a Tequipment cage (the minimum) and use the factory six point harnesses.

For road use the standard 3 point belt with the receptacle outside the shell is fine, and I say that as someone that's crashed the car at considerable speed, into something very solid. I was 165lbs and 6 feet.

As regards getting out of the car quickly. After the crash I've posted images of, the car started to fill with smoke (or I thought it was) it was actually the powder from the passenger door airbag deploying, I thus thought I needed to get out of the car smartly.
Under those circumstances there was no messing around trying to find the seat belt receptacle and it's release button (which would most likely would have injured me had it been inside the shell) because if my torso was thrown against the seat shell with sufficient force to fracture two ribs, I'm pretty sure my hips/pelvis would have hit the SBR with sufficient force to cause some localised trauma.

It's interesting to note that some of you guys think the SBR being on the outside of the shell is dangerous, yet when a fellow Rennlister decides to do a seat install and uses thinwall aluminium box section to raise a seat up and questionable fabrication skills to form a seat belt attachment bracket, none of you batted an eyelid...



I have no doubt whatsoever that if my seat had been mounted using this set up, and my seatbelt attached to the seat mounting frame with this bracket, the outcome of my accident would have been VERY different indeed.

These 997 seats are essentially the same as 996. I would imagine when the parts came out for the 997 they updated the 996 parts diagram.

Atgani

Posting more images doesn't make your case any more valid
I've owned a Gen 1 997 GT3 fitted with those seats (it got used hard too) the 997 seats are different, they're far narrower and nothing like as comfortable as the 996 versions.

hbdunn

Ok i will admit after looking at 996 GT3RS's they came from Porsche routed to the outside. It also seems they changed to the inside with the 997. I still believe this is a safer setup and that's what I was communicating to the OP. We are all entitled to our opinions and I hope the OP will consider everyone's and decide for themselves.

Im reading along too as I’m adding a bucket as well, good info for all.
