Initially, I had bought disc brakes with the slider calipers and the 11” (10.87” I think) rotors. Before they were installed I was able to drop the spindle rotor assembly in my front 14” magnum wheels that were off the car and they fit. I upgrade to 15” torque thrust D 15x7 front wheels and used those 11” rotors. Later I upgrade to the 11.75” rotors, which fit the 15” wheels. The smaller disc rotors did fit my 14” wheels.
