Looking for Autozone's Duralast Black Rotor Revien

Of course its very easy to google a few websites for answers. I guess first hand experience means nothing any more. How many rotors have you measured for thickness variation and runout?

Have you read anything I posted? Of course there is thickness variation and runout. I'm sure you can measure rotors with the best of them, but that does not address the argument here since we both definitely agree there is thickness variation and runout. Now whether or not you call this being "warped" it doesn't matter. The point is, contrary to the popular belief that it's the lack of quality of a rotor that causes "warpage," it is most likely caused by other factors as I pointed out before. I said that rotors don't warp to highlight the fact that when people are faced with "warped" rotors they incorrectly assume that the rotor's quality is in question, when it's more likely that the user is at fault. If you can't wrap your mind around this, that's ok, I will leave it at this.

And I've measured exactly 0 rotors, never had to. But i'm pretty sure Carrol Smith has measured more than you and has forgotten more automotive knowledge than you or I could hope to ever know. I've ran through many cheap blank rotors on both street and track, and my personal and anecdotal experiences agree with what carroll smith had to say on the subject.

Basically, if you're after function, get the cheapest blank rotors you can find, choose the right pads for your application, bed your pads right, use your brakes properly, you'll be fine.
