More correctly, the difference between the face of the rotor and the hub
flange section. If you lay both out on the table, flat, you'll see one is
"higher" than the other. This dimension also ties into caliper mounting
position, which is why that swap won't work. Your caliper wouldn't be
centered over the 10v rotor.

You'd need to swap hubs/brg carriers. They're 2pc struts, so the strut tuabe
can stay where it is.
