too late if you've sent them but generally speaking even if they are rusty BUT evenly rusted, (not warped!) you can reface them perfectly well whilst still on the car.
jack the wheels off the ground then get someone to sit in it and rev it in gear.
use a very thin 1mm cutting disk in the angle grinder (this flexs a little but still has a general flattening effect) and with the disk spinning the grinder creates a new face removing even deep pitting
Mind you don't get wozzerated for suggesting such a dangerous practice. Grinding on the side of a normal flat-sided cutting disk is a bit risky but that's a good way to blow the center out of a thin disk.
