Only had these on the car for about two weeks - made as a reasonable "big brake" upgrade to a 2011 Sonata Turbo. (Bought the 12.6" rotors designed for the Optima Turbo - direct bolt on.) After bedding, these rotors combined with Hyundai XG350 calipers and mating Hawk HPS semi-metallics stop the car far more effectively than OEM. Very minor groan at certain lower speeds - to be expected with semi-metallic pads - but otherwise whisper-quiet and effective power. Absolutely no complaints.
