Rotor replacement

Thanks for the advice. Have you ever run into a problem with runout? Wobbly rotors that had to be machined (cut)?

Sure.
I professionally wrenched for a living for about 30 years.
Back in the day it was standard practice to machine, drums, rotors, when doing a brake job.
Now a days shops don't even have a brake lathe anymore, as modern cars have drums, and rotors, that you just replace.
Throw a way parts.
Remove and replace.
