IIRC, the one with the rubber bushing should be in the leading position. In other words, on the right side where normal direction of the rotor is clockwise, it should be at the latest o'clock. Left side is opposite.
So you are correct from what I have found the bushing goes to the bottom. I don’t know if I am high as a kite or what but I tried the bushing in both top and bottom hole and it seemed to fit better in the bottom hole. On both front brakes. Atleast lol
