Just installed the bushings and pins on all four and thought I might warn those that haven't yet done this mod that you should be careful to inspect the backside of the bushing where the circlip goes to be sure that there is sufficient clearance to allow the circlip to completely seat. If not, just take a wide, flat file and carefully mill off a little of the aluminum casting of the caliper so as to expose more of the bushing. Otherwise, the circlip may pop off if not completely seated in the groove.
