holes vented, im replacing them on my car but i know they are not the
standard so its proving very hard, any suggestionsvwould be great
If the braking system has been modded then your beat bet will be a speed shop, take the rotor in that your trying to match so they mic it out just to be sure.
Look at the calipers. If the brakes were upgraded the rotors and calipers go together. On the other hand there are stock replacement drilled and slotted rotors available such as Power Stop.
