Dealer has offered 21" Turbo wheels. However, he made a comment that they had come off a Cayenne. Does anyone know if these are interchangeable. I thought I had read they were a different offset etc.Thanks
They are not interchangeable.
The offsets are different, the PCD (diameter of the circle made by the bolt holes) is different and the bore (hole in the middle of the wheel) is a different size.
They are, however, both round.
About as incompatible as you can get.
I'd walk from this level of BS / incompetence.
