I have purchased a Cayman race car and need to identify the hubs currently on the car. The part numbers are 997341657AR AS001 N/S and 997341658AR AS001 O/S Made in Germany. I have tried many breakers who can supply hubs which are standard Cayman hubs which have the first part of the number but are made in Italy and do not have the AS001 Made in Germany stamped on them. My local Porsche dealership advises its only a casting number and they can’t advise what Vehichle the hubs are from! I’ve attached a photograph of the ones I’m looking for, there are two bolts holes in the top and a deep hole for the bottom ball joint which is clearly different from the standard ones that only have one bolt hole in the top and a shallow hole for the bottom ball joint. Any help would be appreciated.
