Conversion to Porsche saddles

Hello Sorry, I just came over from the Golf 2 Forum and wanted to ask a question quite humbly… Maybe someone can help me here?! Since there has been a certain kinship for a long time and there are also various joint “projects” of the two companies, moreover my vehicle can wear the paint from Zuffenhausen since its birth (L94E) , it is now near to convert to a real brake …! There are adapters, so that you can a Porsche Saddle a In such an E*** auction for such adapters on the Golf G60 wheel bearing housing, a part number of Porsche Boxster saddles was given, which should fit on the 280mm VW disk installed with me. (986.351.421 / .422) Now I have also discovered saddles, which have practically the same part number and also listen to the description of the brake disc size “suitable”, are only of 993. (993.351.421 / .422)http://cgi.ebay.de/…/2 50861884124?… I only know the following: 993 or 986 in the TN stands for the 11 (993) or Boxster (986) 351 stands for VA 421 (422) stands for the right (left) Now is only the question: Are the two saddle types the same? Bzw: Can anyone explain to me the difference between the different saddles? Thank you! Greeting!
