When I asked Design911 this question they stated that they had no approval, or have been subjected to any tests at all.

Quick update. I had the car out for a run over one of my favourite roads. Helmsley to Stokesley. Awesome moorland blast.

The seat was a revelation. The difference over standard seats is incredible. I finally felt like I was sat in the car rather than on it. I always felt the hardback seats where to high. The way it holds you in the corners makes the connection so much higher. I can finally see the top of the dials too! They are a brilliant upgrade.

As for the GT shifter I got that from here:

Not cheap. But a real thing of beauty.


That is not cheap! Does look lovely though.

Will add making one of those to the 'project' list...

Seats look great!

D911 is woeful.

There was a lengthy discussion about the quality of the D911 Seats, on here and PH as it goes. Uptake was a very well respected man that makes Pork race ready uses them and has no concerns over safety. I took the plunge off the back of all the chat.

This makes interesting reading and in my eyes confirms there is little issue with the afore mentioned seats.

I'd also read those discussions and felt they where safe to use. Obviously hence buying them!

My passenger seat has arrived so that another afternoon taking up with fitting it this weekend. I dare say it'll be a quicker process the second time around!

Question now is do I sell the hardbacks? Any idea what painted hardbacks would go for. Both in good condition.

^^^^^^This!

PopPopBangBang was the man in question, good enough for him, deemed good enough for everyone was my take home.

Must say I do wonder if I shouldn’t have got the leather ones.

I recall that thread and even contributed to it Smile Well, pays your Money takes your chances. I’d wonder what an insurance company might make of it though.

D911 are a complete shower, gave them another chance a few weeks back but nothing had changed.

Back in the day on PH I originally registered as Richie200 and was quite heavily involved in that thread. I'm also involved in various NDT techniques on a daily basis in aviation (eddy current, x-ray, dye penetrant, thixotropic, MPI...). On this basis I can concur with the sentiments of Popbang… So much so in fact that I have a set of the D911 Carbon leather seats in my own 911. Meeting test standards is not always a good indicator of the best quality is all I'll say.

I think the point may be being missed. It seems one seat was tested in 2016 by a consumer with access to some test equipment. No testing by the manufacturer that they or the retailers can be bothered to mention so not sure how one could know the others off the production line months and years before and afterwards would meet the same standards. Obviously the manufacturer’s processes are so consistently robust they remain a secret..or, no one is checking or cares enough perhaps.

Should the worst happen you’d imagine the insurance company’s engineer may notice this.

If your happy that’s fine too. Rather have a Recaro with a sticker on it for less money personally.

I think it’s you that is missing the point, did you not read the part about the FIA testing standards and how Recaro had a whole heap of seats recalled?

You seem to be dismissing the testing of the D911 seat and ignoring the issues Recaro had, if there standards were so consistently robust, why the recall?

I passed no particular comment on Recaro’s standards but obviously they have some evidenced by the fact there was a system in place that facilitated a recall.

not sure how you would even know if there was a bad batch of the D911 seat as they have no testing they want to tell anyone about.

Is the chap who tested the other seat underwriting it’s safety credentials...

For the sake of context....

Have you ever seen, sat in, or driven around a circuit in the D911 seats?

I’ve seen some, they look fine. Wouldn’t consider them personally for the reasons outlined. Have tracked in all the others though, 997, 996, Recaro PP’s Crashed in a couple too. Perhaps I’m over sensitive but ***** does happen.

I have the 997 GT3 style seats in my car, I bought then second hand
off Ebay so I dont know where they originated.

I was expecting a crappy quality seat to be honest but I was surprised
when they arrived. I build & run a lot of rally car's & I cut my teeth sitting
in bucket seats and the GT reps look as good quality as any FIA approved
seat.

Example, take a seat made by OMP, Sparco etc and the 4x M8 mounting
points are nothing more than nutserts/rivnuts drilled into the glass fiber.

The GT3 reps have 4x machined steel bushes with the composite sandwiched
between.

Also, I gave my seats to a very good professional trimmer to re-trim the centers and he claims the foam is a very expensive high density foam
that even he could not source.

Glad you’re enjoying your seats Sackerley!

I always say the 2 biggest mods you can do to a 996 is Coilovers and bucket seats. Both transform the car.

Regarding the D911 buckets, I was happy to use them but we all need to weigh up what we are comfortable using regarding any lack of certification etc.
In all honesty I wouldn’t choose to crash in them obviously, but at the same time I was happy with the risks as they were great seats and you can limit your risk of an accident to a certain degree.

Had I had a big crash before where the seats really came into it, I may not be so carefree.

The comments about them being narrow are very true. I’ve a 32 inch waist and they were snug. The genuine GT3 items have more room, but at £3000 fir a used pair vs £1000 for the replicas it’s a no brainer for most of us.
Plus they are a lovely looking seat.

Gratuitous pic of mine after their retrim in grey.

Thanks Marky.

They really do make a big difference to how the car feels.Quite surprisingly so.

Your seats look great in Grey too Thumb

Which mounts / runners are you using?

Hi Sackerley.

Yep it’s amazing how keyed into the car you feel in those seats. Night and day compared the normal seats.

In the pic above mine are on the D911 sidemounts and runners, but there was play in them front to back and they felt cheap.
So basically you use the D911 sidemounts and use your original 996 runners for the rest. The holes down over through the sidemounts lined up with my Porsche runners perfectly. Even if they didn’t it would be nothing to line up the front or rears and drill new holes in the bottom of the sidemounts, where required.

So you have your standard levers etc under the seat and a much nicer “factory” fore and aft mechanism. They’ll also be sitting nice and low too.

Only issue we had was the bottom of the seat shell at the rear was just fouling the rear bolts that go down through the rails, so when pulling the lever to move it forward, the mechanism would pop out of position. Simply adding 2 washers per seat between the bottom of the side mount and the top of the Porsche rail at each rear hole (2 per seat), lifted the seat 2mm so it stopped fouling and worked perfectly.

The seats felt so much better on the Porsche rails plus they looked factory standard with the original levers down there etc.


Covered here on my thread -

http://www.911uk.com/viewtopic.php?t=118164&postdays=0&postorder=asc&start=260


As I’ve said, when bolted in using the Porsche runners they looked and felt so much better. Cool
Plus you’d save money from not buying those universal box section style runners.


PS. I’ve seen it looks like you’ve done the same. Proper job! Thumb

I ride Alpine downhill on Light Bicycle carbon rims which I suspect is probably similar to using D911 seats on a track day. YOLO, as they say.

Thanks for the Marky - I'm glad I stuck with the original runners now.

Hi Sackerley,
I'm on the lookout for a pair of hardback sport seats. Unfortunately only interested if they're black. What have you got ? PM me offline if you'd prefer rather than take the thread off track.

cheers,

Jamie
