Hey there,
Might I suggest visiting the Rennlist or Pelican Parts forum. They usually have a lot more technical posts dealing with issues such as yours. I remember when I needed a recommendation for a clutch, I received info on one of them. Unfortunately, I have an air cooled PCAR and the company that I purchased my stage II PP & disk from do not make them for newer Porsche's. Good luck with your search and Happy Holidays...
