I would avoid Centric blank rotors & Carbotech 1521 pads. I put a set on in May and after maybe 1k miles they were squeaking like crazy at low speed. After about 3k miles there is visible wear on the rotors. I don't know if it was the pads or the rotors but I won't be using either one anymore. Those pads were stupid expensive too, big waste of money. I'll probably end up replacing them after around 5-6k miles when they're no longer usable.
