It also means that the material that is spinning is not balanced through the assembly, and can lead to a cracked rotor, a long pedal, and unusual Brake Pad Factory wear.In conclusion, are high quality rotors a waste of money? Like tools, good quality parts are never a waste. On average, a motorsports rotor will outlast a parts store rotor by long enough to justify the increased price.The increased performance is nice to have, too! Parts store rotors have been known to work; on the other hand, they have also let a lot of people down.Not to go too far off track, but that is why you see 15-16″ carbon ceramic rotors on many production cars the manufacturers need the increased size to get the performance!The benefit of carbon is that it will outlast an iron rotor and have a larger temperature range. Anyways, back on topic (sorry).Iron is one of the densest materials in the universe. The purity of the irons casting makes a considerable impact on braking performance.Rotors that are cast in China are known to have quite a few impurities, and are sometimes even labeled incorrectly (anyone that has dealt with 304 Chinese stainless will know what Im talking about!)These impurities will have a detrimental effect on braking performance with decreased overall braking torque, decreased rotor life, and unstable tendencies at thermal capacity (aka exploding rotors).I like to find rotors manufactured and cast in the United States, where there is a higher casting standard.Knowing that the car doesnt do more than 30min sessions, Im daily driving it and I have no brake heat issues. Are these people right? Would it be beneficial to get expensive performance rotors?Im on my second year with the HP+ pads and Im also curious about trying something else. What Semi-metallic Brake Pad /rotor combo would you suggest for my current setup?
