R1 brakes unusual wear pattern?

[rayofsi]

So both my rear rotors look like this. Is this wear unusual? Other bbk owners? R1 owners? This is the 3rd truck/car I put bbks into, and the only one like this

check the pad engagement surface on the rotor. looks like the pad doesnt cover the whole rotor face.

Yes, ive seen this in other manufacturers.

I think general consensus is, if the pad doesn't fully cover the rotor surface at the inner diameter part, then that's fine. If the pad has an overhang at the outer diameter of the rotor, then that's not good.
