First, we try changing the position of the rotor on the hub to alleviatea high spot. You have four chances to make it better. Sometimes thisprocess helps, and sometimes it makes the runout worse. We also trychanging the rotors from one side to the other if possible. With ourdirectional SSBC Turbo-slotted rotors, we didnt have that luxury. Youcant change the position of rear rotors on the hubs because of thedrilled holes for emergency brake adjustment unless you want to removethe rotors for brake adjustment.
