I have glazed my brakes badly in this month and they squealing horribly. Since I will be doing pads and rotors I'm going to jump up to the bigger 13+ pp brakes since mine is a 10 non pp. I just wanted to make sure that a 13 pp brakes are what I want. Are the 13 pp brakes the same part numbers as a 16pp or did they improve up on them again?
