My friend has a set of OEM Porsche 19"s from a guy he worked for that had a Cayenne that we are trying to sell as neither of us have a Cayenne of our own, let alone any Porsche. We are trying to sell these but if they work on any or some Porsche cars as well, not just the Cayenne there would be X amount more people that could use these wheels. Are the bolt pattern and hub offsets comparable to the usual Porsche car fitments? Being an SUV I would think not but then again I could be wrong.
