They look like Recaro "wingbacks" from an RS model but they could be some sort of aftermarket replica as well. Or they could be the factory ones with the leather changed (I'm not sure they came in that 2-tone, but we never got them here in an Mk2 I don't think so can't say for sure).

Here's some more info on the "wingback" seats:

Ultimate Guide to European Wingback Seats for Audis

One of my favorite (and most rare) mods to my 2012 Audi TTRS was the European Recaro Wingback seats (often referred to as Wingbacks, or Euro Recaros) I had imported from the UK. These were never so…

They're Audi 'wingbacks' from Recaro. They were an option for loads of different models including the TT[emoji1303]

Really nice looking seat for the TT

Can't say I'm a fan of the colour.

 

The European MK6 Golf R also came with these seats. A person in the US was importing them to for several years at $6,000 a set delivered. However, they didn’t come with airbags so some reworking was necessary.

 

As others have put - Recaro wingbacks
Option in any TT if you wanted them bad enough to pay the price - not just the RS.
My TTS for example was an original fitted/spec with Wingbacks before I removed them (TT photo below)
Non RS models spec'd with wingbacks didn't have any stamping/branding but still the unique TT pattern in the seats - so the ones posted look to me like TT spec seat

The style of the stitch/panel shape in the TT specific pattern, 'Audi' (There is a few slight variations between RS4 / RS3) wingbacks, & Volkswagen version is very noticeable to those in the know.
For those who haven't seen it - easy comparison side by side:

Colour looks 100% not standard though - these have definitely seen a trip to the retrimmers OR something like a set of Seat Skinz fitted covers*
*stand corrected - possibly exclusive insides

Any particualr reason why you didn't keep them ?

 

I don't know anything about these seats but that car does have an exclusive interior as you can make out the silver badge in the door card upholstery, so it is feasible

 

I did notice these badges but had no idea what they were for..

Would seats from a 2020 RS3 fit in an 8J? These look a little dodgy as they don’t even have power buttons.

 

Yeah these are a manual version. All the ones shown by Barr_end above are manual as well, so did they even come in a powered version?

I'm sure you can get 8S seats to fit given someone put TT seats in a Nissan Murano or something not long ago and there was a post here about it lol. How much work, fabrication, rewiring, etc. might be involved with that, is another story. But I'd think it'd be easier than putting them in a Nissan, so at least you're one step ahead of that!

 

I’m wondering about the provenance of these seats. I can’t believe they came from a 2020 RS3 US car. Certainly all came with power seats. Could one just switch out the bases?

 

I started asking the seller about the seats above and suddenly they were removed. He claimed they came from a 2020 RS3, were electric, and had airbags. You can easily see the first two claims were false and given they were in NYC I’m guessing they were stolen too.
