I got everything in the mail. It looks awesome, I am very happy with it. There's just one small problem. The brackets are designed to be used on a 6 lug truck, with Toyota rotors, which are more shallow than these mustang rotors, so the rotors are off center to the caliper. I spaced the bracket out 1/4" and it looks like it'll work, so I'm gonna have to cut a spacer to go between the axle flange and caliper bracket.
