My OEM rotors had stress cracks almost all the way around in each front disc, for high speed stop and go the factory rotors just can not dissipate the heat fast enough, and with no slots in the discs serious brake fade from glazing was occurring so I don't believe just pads would have solved those issues. IMO.
