Do a seach on FCP Groton.
Some like them, some not.
They do not clearly say the maker, they say made in Germany by Hamburg Technik.
I prefer Meyle or Lemfoerder or MAPCO.
I buy from MK Autotechnik in Germany usually. They clearly say what they offer. The owner of MK Autotechnik is peter Meissner, he owns an E32 750iL an E31 850 and also an E24 6 series. So he knows what he talks about.
