What is the difference between the C4 front and rear rotors?
The C4 12 inch NON-HD front and rear rotors are about the same except for offset. They are the same thickness and there shouldn’t be a noticeable performance difference between the two rotors. The rear rotors allow for more room for a bracket so they will work with my bracket design. If you want the 13 inch C4 HD brakes you will need to use the C4 13 inch HD front rotors and a thirdgen f-body 1LE rotor as a hub.
