No I've explained this, the difference is in the N16/P11 knuckle. They mount a little closer in than on the S**,R** and Z32. Hence why if you try and mount a Z32 caliper on the n16 with standard 280mm discs the edge of the disc will foul the inside of the caliper.
This is why DB-Power thought 310mm would work on the N16 for the 315mm bracket. But seems he over estimated how far the N16 holds the caliper in. Rather than 5mm it's more like 2-3mm.
