I don't know about them making a loss, but I expect 182 seats aren't cheap, unlike Cup seats. They were a much more expensive option in 182 Cup, than the full fat 182.
I don't know if this is true, but I was at a local Renault bodyshop the other day and we were discusing how Trophy dampers are impossible to source, the parts guy commented they are having the same problem with the Recaros.
I'd guess Renault purchased a bulk amount from Recaro to cover all the cars which were to be fitted with them, and a few spares, which have now been used up.
Renault have never sold the Recaros seperately.
