Edge and MKX use the same brakes as the 3.0 MKZ and the 17 to 19 Sport. Only difference is the front rotors is the Edge and MKX use a rotor that vents to the inside where as the sport vents out the front. I ordered mine I ordered rotors n pads for a MKZ 3.0 and rears were for a Edge. Fronts are 345mm and rears are solid 300mm. Now there is a posable upgrade, to what the 20 to 22 Edge has, but I'm still working on that. They have 14 inch rotors in the front that vent inward and bigger calipers, the rear has vented rotors that vent outward, look to be around an inch bigger but with the same caliper. I'll know more in the weeks to came when I take the time to look more into it, but like I said. The MKZ 3.0 has the same brakes as the 17 up Sport, everything else is 300mm inward vented. Far as the Fusion goes the Sport is the only one with the big brakes on the front, every other sub model uses the 300mm rotors.
