I don't think I've ever had a set of rotors turned. I've never grooved a set
badly and new pads on untreated rotors have adapted without incident for me.
I just try to bed them in gently and take it easy for a while afterward.

Kent, please explain just how your State inspection inspects rotors
in general and UFOs in particular to declare them unsuitable. Same for their
criteria for pad rejection. I'll bet they just feel
for a little rotor ridge, no quantitative measurement. IMO rotor
minimum thickness specs are just BS, a CYA spec designed to sell
rotors. Never, ever have rotors turned! The lathes for doing so ane
not maintained and will introduce much runout at the cost of much
metal lost. Rotors wear true, worn rotors are always better than new.
My 200-20V has great original rotors at 225K, and will never be
changed. No required inspection.
