oe for that car's flex discs were jurid. I doubt oem is any supplier for mb or Porsche. however, URO is now an oe supplier to jaguar.

I have access to oem brand for some parts and have not had an issue-yet. I won't use their flex discs. I get febi or jurid.

just get the real part. if that cheap one comes apart at speed, the d/shaft comes off and that's a real mess, transmission and airbag-wise. not worth it. good luck, chuck.
