Past comments suggest that different wheel diameters front to rear is a bad idea; however, Porsche does this on two or more models. I want to put 18s front & 19s rear on 2007 Cayman. Problems? Thx.

See above.  Will 18-inch wheels in the front and 19s in the back cause problems (2007 Cayman)? Porsche puts different diameter wheels on some models from the factory.  Thank you.
