I was going to replace my rotors, but the machine to limit on them is 1.230". Mine were at 1.380!! You never get that kind of material to potentially turn off. I bet I can turn them 2-3 times more before they're out of spec! Why can't they make anything like they used to??? I turn rotors all day, typically the OE rotors will have maybe one turn in them and they're done, .020" or so is all you get. .150" is unheard of!!
