I have brembo slottd and cross drilled rotors, and used to have on Hawk pads. They worked great, but the rear pads were noisy; could have been the slots and holes, but I replaced them with lifetime pads from O'Reilly's and there's no difference for the street once you have good rotors. Hawks will make the biggest difference when they get hot, like a road course, they work better when they're warm.
