Looking at buying a 2012 gt cs and wondering if the the lips are rolled from factory or what because this car seems to have them rolled but I've been out of the mustang scene for 3+ years with my last one being a 2001 v6 vert
Yes, Ford factory pressed when forming the corner panels.
For whatever reason Ford, Chev, and Chrysler continue to used the old corner panel "Truck" blueprints. One day they'll wake up and go with a European fender well designed and close those wide open fender to tire gaps.
