ok so when i bought my z, it already had the c5 front brake swap done, and my rotors recently warped, so its time to replace. question is, will stock c5 rotors fit, or is there some kind of machining that needs to be done on the hub to make them fit? i have taken the rotors off before, once the caliper is off, you can just pull the rotor off all by itself, so my intuition tells me that the stock c5 replacements will work, but im not 100% sure

 

Yes you would use stock unaltered rotors. The only thing to be aware of is the fact the turned down hub must fit inside the hat portion of rotor; so that the rotor is flat against it. I have had some that didn't.

 

JUST what i wanted to hear!
