After several postings and a few weeks of hard labor, I got my 15x7 Rally IIs done. When I put them on my '67 400 convertible the front wheels were hitting the calipers. The wheels mounted on the rotors fine, but they would not turn. My car came with factory disc brakes, but I'm not sure about the 4 piston calipers. Since breaking is kind of important I want to stay with my current calipers and I really want to have the Rally IIs on also. Has anyone else dealt with this? Can I grind down the calipers? Suggestions are greatly appreciated.
