Pulled the tardme pin on these, look to have recaro mounting brackets etc from what I could see, dont look too out of place in an E87, plus air lumbar, heating, and ass cooling fans. Oddball JDM recaros, look to be aftermarket only - SP-JC.
Cert to install them doesnt look too tricky, removing airbags being the main hurdle. Rest looks fairly legit. The car they are installed in is a bog standard poverty pack prelci 120 wreck.
