I have taken some measurements, they are all from the rear face to the base of the hex, there is a little error in absolute values but they paint a clear picture of how they compare

Front Standard 21.5 mm
Front CNC 21.3mm

Rear Standard 27.5mm
Rear CNC 30.5 mm

So it seems the rears need to sit 3mm further out. I didn't compare the overall width of the wheels.
This extra offset can either be achieved by building up the hex area or giving the wheel face a deeper dish
