will the 599 challenge wheels and tires fit on the california.
When I got my Cali in 2010 I had the dealer install the "challenge" style wheel from a 612 to see how they would look. They fit, so I would assume the 599 wheel would fit as well. I thought they looked pretty good, but the younger guys in the garage insisted that the factory Cali 20's looked better which made me feel better about sticking with the originals.
