So plugging the stock seat belt rec into the car gets rid of weight sensor code or it just does not light up?

Thanks for the write-up, that's great! I just bought a set of these seats too! Installed them in my 991.2 GTS today. I also need to solve the airbag light. I'd love to meet up for coffee maybe sometime and discuss?

This is for the seat heaters! I've tried them, and they work!

I agree with all of your points, especially this one. This is the biggest drawback so far, but otherwise they are amazing!

Also, you've probably noticed as well, but the Ultimate Cup holders don't work great with these seats. The forward/backward seat adjustment lever gets in the way, and it makes it hard to adjust the seat (especially on the passenger side). =(

weight sensor code & does not light up seems like the same thing. But yes, nothing lights up. In sort, you're basically telling the car you still have the original seat in the car but in reality the seat itself is different. Again, not sure the functionality of the side airbag though.

Love to. I'll be back home on the 14th. We can maybe meet up at Alice on Sunday morning.

Did you also reach out to Ed for the side bolster cover? He contacted me asking if that's the source of my seat and someone else inquired him for the seat cover. If so, black touring is the stitching you'll need to match.

Nice! I wished they were occupancy sensors though!

Thanks for the details. They are such great looking seats and a relatively comfortable seat but not as comfortable as the 4 way as you mentioned.

I would probably have them in my 997, however two issues, one of which you mentioned have prevented me from doing so. The first being that they sit too high. With the 4 way seats I have a couple of fingers if not more between my head and the roof in a sunroof car. However in the bucket seat car my head is touching the roof. The second issue is how much the seat is raked. The bottom cushion has a very steep angle which does dig into the back of your legs a bit more than a 4 way seat car which is a bit more flat but is still supportive. For me the 918 seats are still the most comfortable buckets that I have been in, although I would like a chance to sit in the CGT seats. Those should be similar to the 4 ways in the seat angle and I believe they don't sit as high as well, but they are lacking the side airbag which is a big deal especially if you are daily driving the car or using it more than a weekend car.

Yeah, sounds good! Let's coordinate on DM.

Didn't know about this. How do I get a set of side bolsters covers? I'd like to get them for both the driver and passenger side.

…I think you and I are thinking of the same thing. Re-Use the GT2 bucket anchor, retrofit the original cable harness & receptacle to the GT2 bucket anchor without taking apart the receptacle. I think this might be the safest way. Obviously my long term is to fix the buckle issue so it's not putting stress on the seat. I'll take a look when I get home.

I think John Gaydos (now at Soul?) has been involved in or knows about this upgrade. Would be curious for his thoughts, if he's willing to share.

Interesting idea. I guess the questions become...

What is the second part of the 2-part harness reading? An occupancy sensor seem logical, but prompts a question as to why you aren't getting an airbag light while using the US harness with the Euro seat unless the Euro seat has the sensor but (for some reason) no output for a Euro car?
With the above scenario...will the car register no one in the passenger seat when the US buckle is buckled but hidden under the seat—and fail to fire the smart airbags for a passenger in the event of an accident? Or will it do the opposite, and fire the passenger airbags even if no one is over there?

Should be discoverable with the help of the great Mooty (or some other modern-day seat hoarder.

Drove a 991.2 Cabrio with them (with heat!) years ago and liked them, and found them seeming to be lower in another 991. Could be wrong, and would be curious to hear others weigh in on this.

If too high, I understand there are aftermarket rails to get them down.

Reach out to @Crazy Eddie . He's local in Los Altos so you can pick it up from him.

I actually have no idea how the car would see it as. I "believe" the whole functionality of the airbag is based on the occupancy sensor; hence, you get the passenger airbag lights on or off above by the garage opener. BUT given the current situation I'm not sure if it's on or off. I also forgot to check if the "passenger airbag" sensor is on or off above the garage opener. I guess I'll check when I get home.

Assume he's on the forum. What's his username?

Ah, that's a key data point and, given that light's location, I must admit I rarely look at it. I looked at it more often in the GT4, when I was using a child seat up front, but I just about never look in my 911, or notice it on or off as I have in some of our other cars.

Could provide a key data point here, as I am wondering if the passenger occupancy sensor is in the Euro seat. Odd that there wouldn't be one (as who wants to waste good airbags), but similarly odd that Porsche would make a buckle without wiring for one. Will be interesting to see what that light says if an adult is sitting next to you while you're driving the car.

Thanks Pete. I will have to see if someone local already has lowering brackets installed on them. I know people with the seats, but finding someone with the brackets may be more challenging.

Also, just got my 000, excited to start reading! Hopefully you guys can feature the 997 GT3 at some point, I would really enjoy that. Excited to read more about the 997 GT2.

What if you disconnect the white connector on the 2x sensor connector (i.e. effectively making it a 1x wire sensor)? If that works, then maybe you can just get the driver's side 1x buckle and mount it on the passenger side?

I will check, however I believe my mechanic moved the electric module from under my OEM passenger seat and moved it to these seats. That apparently resolved the issue. For some reason that was not necessary on the drivers seat. I will ask him this week , however I know that he did move the electronics from the factory seats to the GT2 Bucket Seats. When I want to put the OEM seats back in, he would have to move the electronics back . The Inserts were from Kim at P1Designs , who did an amazing job.
