Hi everyone, I‘m doing front pads on a 2017 BMW F31 with M Performance fixed calipers. The kit is a Ferodo Premier and came with 4 backplates: 2 plain, 2 with cutouts. I checked and none of the pads are directional, all the same. On the car, the old pads all had plain backplates. Can you help me figure out which which ones go on the inside/outside? Thanks!
