Just installed new pads and rotors. Both are aftermarket. I didn't even think to check, but when I came back in from braking the rotors in, this is what I got...I had a small lip on the old rotor, but nothing like this. The edge of the pan goes to the OD, but as you can see it falls short on the ID. Waiting on vendor to get back with me, but what are your thoughts.

Also, both sides are the same outside, inside, driver, passenger side rear brakes.

Thanks in Advance,

MrN
