Good technique, but I already measured run out on the orginal disc's from AP. They were about 007" which was too much. Stilen has been working hard with me to figure this problem out. They rebuilt the strap drive on those discs and still no difference. O actually ended up getting new discs a year ago for this problem from AP and the problem is the same but the vibration is a little better on the second set. We'be even tried a different set of AP calipers with street seals and removed the piston springs to allow less pressue on the disc while at cruise.
