Its the rotors from their big brake kits. To many track events and improper bedding procedures pretty much FUBAR'd both front rotors.
What would be a good racing brake pad? I typically go to high speed road courses / tracks here in the Midwest. These replacement rotors will be used for track only events. Will use the old ones for street.
