Talked with a knowlegeable person (who will remain nameless) who said they were German made, previously as part the Euro dealer installed RS (Reinsport = Racing Sport) option but now for BAT. Asked who made them & he said that they are not labeled by this company & he wasn't supposed to advertise this but "if I guessed that the company started with B, I would be correct". German B = Bilstein, unless I am missing another B German shock company.
