I just spent $263 at RA for pads and rotors for pickup. Nothing fancy, Akebono pads and Wagner coated rotors. And of course RA crazy shipping charges. Seems like a lot. So with smaller vehicles you can get good rotors for $35 to $40 if I remember. But with $100 rotors for my pickup it would seem turning the rotors might be reasonable even if if costs $20. Not worth it on a $35 to $40 rotor but worth it on a $100 rotor. Not sure anyone turns rotors even if you wanted to pay $20/rotor. From a world waste perspective, buying a rotor that weighs 20 lbs and tossing it when it weighs 19.95 lbs seems a waste. I assume the rotors are melted down for new iron/steel.
