The Touring Backseat Project

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. Its 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.
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.

For anybody considering this I'm selling all the parts from my recent "rear seat delete" project here:

Our kit uses OEM Porsche restraint system, is fully reversible, can be installed by a DIY-er in about 2-2.5hrs, and made in the USA.

There are a few guys doing rear seat deletes in the 992 sub. Seems like a much cheaper option to do a swap vs spending $11k on all the parts from PAG.

@ZIP22 What exactly is required to do to install those? What's part of the package? And can it be ordered without the branding?
2) There's no branding of the seatbelts or carseat, unless you want it included.
The branding you see in the pics was when the car was on display for Monterey Car Week. The basic kit includes two OEM rear seatbelts (black color), two OEM seatbelt buckles (black), two OEM belt trim pieces (black), customized hardware, customized tools, seat mat (in black) overlay. Visit us at www.GT3Belts.com for more info, pricing, and availability. Or you can email us directly at gt3belts@gmail.com3) The GT3Belts kit can be installed in about 2-2.5hrs by a mechanic or experienced DIY-er. Kit is fully reversible. We provide a comprehensive step-by-step instructions with the kit.
4) Just like Porsche exclusive manufaktur, we offer a myriad of customizations for an additional fee.
From custom color seatbelts, different seat mat material (OEM color alcantara, OEM color leather, or different plaid OEM fabrics/patterns), and embroidery. We also provide NHTSA and FAA approved carseats that fit the narrow 911 rear seats. Carseats are also available for unique material color customation and embroidery.
5) LWB and rear seatbelt delete peeps we also offer customized rear seat mats as well.
6) Mods we are working with Heather to get a vendor account.
Customizations galore!
Now you have the ability to take the kiddos or small adults in your GT3 without having to take out the minivan.

Hey Shack993 - Thank you so much for the level of detail included in your posts on this process. I'm brand new to this forum. I have a 992 Turbo S and am going to be selling it and getting a 992 GT3 and adding rear seats. Wife thinks I'm crazy and I am, but who doesn't love a good project 
Question - I've used the google translator to email manually and also via the elfermotors "contact us" part of their website. I wanted to see how you were able to get a hold of them? I'd like to get that bracket ordered asap.
Again thank you so much!

OP here. After a super long story with a very unscrupulous dealer, my touring is no longer.
I have elfermotors kits/brackets for both 992 and 991 GT3's that I will not be using. DM if you want them 50% off. Never used/installed.
Drizzly me if you want to GT3 story. Its a doozy.
