You know that the Elfermotors solution is Germany TUV certified? The seat belts are bolted into same holes as a standard carrera? The seat belts are the same as a carerra?
Interesting but seems like alot of time/effort/money spent on backseats that are and always were practically unusable from the start.
Depends on how old your kids were. I have fit my kids in the back of a 991 Cab and then when they got too big, in the back of a 997 Turbo S Coupe. My daughter still fits back there but my son is now 6'2" and...no way.

Also disagree.
Have used my 997 gt3 with rear seats hundreds of times with my kids since 2016. They are now 15, 14 y.o. Since my son is taller than me (now 5'9"), he has to strategically sit behind my wife.
Of all my sports cars, my kids prefer the rear seats of my gt3 than the rest.

Hey everyone, I posted here awhile back but then sold my 2018 GT3 Touring when I took delivery of my 992 C4S. I did piece together the complete set of parts to do this installation on a 991 GT3. I installed it into my car but then took it out for selling it. If interested just DM me. I have all the parts and receipts, I think it was around $12k in parts, particularly because almost all the parts are new, especially the black leather/black stitching rear seats that I ordered from Porsche in Germany. The installation takes a good 6-8 hours to do but it isn't hard. I'm in the process of moving everything out of my garage for renovation so when I get a chance I'll take a bunch of photos of the part and do a post in the for sale section of the forums.
I think some of the parts are interchangeable, but others are not for certain. For example the seat back rests look the same in my 992, but the bottom seat is different. Here are a list of the parts required and where I sourced them, perhaps you can check them against the 992 ones and see what is same/different.

So I finally got my Elfermotors rear seat kit approved in Switzerland. Elfermotors claims that their solution is TÜV approved for Germany and they have documentation for that. For Switzerland, different story.
The anchor points for the seatbelts are the same as for standard 911s, so they just use a standard seatbelt for that. BUT, the GT3 (winged and touring) has no anchor points for the rear seat belt receivers. Elfermotors’ solution essentially is to drillsinto the chassis and create an anchor point with a round plate in the outside of the chassis.
This solution did NOT work in Switzerland and I needed my workshop to re-engineer this to a much higher standard to get the rear seats registered. My workshop also voiced concerns if the Elfermotors anchor points would really be strong enough. It’s a bit of a shame, as Elfermotors could quite easily engineer this bit a bit better, as they have an otherwise great (albeit stupidly expensive) solution.
So in essence, with a skilled workshop and them having some insight into how licensing in your country works, you should be able to get this approved almost anywhere (Switzerland is notoriously strict about these things) but I would not rely on the Elfermotors passing without further modifications.
To me in the end it’s worth it, as I really have a unicorn car with the approved/registered seats, but be prepared to spend some extra time and money to get this done.
Another aspect to consider is that the drilling of the chassis ;two small holes) into what is essentially the engine bay results in some engine noise ;not the good kind) making it into the cabin. I am very OCD on noises and I did notice a very slight difference. So, when my workshop did the necessary modifications, I had them add some extra sound insulation around the area where the anchor points are fixed, solving that issue.
Having had a lot of work done on my cars, it once again proves that even seemingly small changes carries out by specialists can result in some unexpected issues and if you want a ‘perfect’ solution, get ready for a long process.
I'm not entirely sure what the laws are in the US about this, but there are half a dozen companies that make seat belt anchors for custom hot rod cars and race cars. This is what I used for my GT3 Touring rear seat belt receivers. My 911 had the holes there already, but no mounting plates. There are options available that weld in or mount with fasteners. It's best to work with a custom shop with experience building road legal hot rods as well as race cars that meet US safety requirements.
Here are some examples of seat belt anchor plates made by some US vendors. Places like Summit Racing or JEGS sell these.

Yes my shop didn't like the Elfermotors solution either and used backing plates which were apparently "fun" to get in place under there.... can't say there is any noticeable increase in noise as a result.
