Centric C-TEK OEM Replacement 1.8L Miata Brake Rotors

We've come across many of cheap OEM replacement rotors in our days as Spec Miata racers, and the one cheap rotor that always stands up to the abuse of SM racing is these Centric Standard rotors. Sure, you can spend more on rotors that claim to be better, or you can spend less (not much though) on rotors that will save you a few bucks, but beware, that couple of bucks saved might turn into $75 wasted because those ultra cheap rotors from your local parts store do not work right on the track, forcing you to go back to these Centrics anyways!
