Igot the same kit on my car and the thing you got to watch is that the pads don't hang over the edge of the rotor. That is one thing the other if you are using a very aggressive pad, like for racing it will always make that noise unless you get some heat in them.Had a mustang with 13.5 inch rotors in the front and 12.5 in the rear and the thing sounded like a bus coming to a stop when they were cold.
