Re: C20 Brake Rotor ?'s
The "V" was used as a minimum thickness gauge. As you turned the rotor, is the V was gone, the rotor was replaced. That was back when rotors could be turn several times. I do not know of any replacement rotor that still have the V groove. Maybe a specialty shop like CPP, ECE, or McGoughy's might have them for trucks, if you really need the OEM look.
