If the rotors that are on the car now are OEM originals, and are still serviceable, why would you replace them? There is nothing available that is superior quality to what is on it now. I am not aware of any non OEM brake components that do NOT come from overseas. Overseas material is inferior, and wears rapidly. I've run these 'snake oil' drilled and vented wizz-bang rotors on some of my other cars, and they lasted less than 25K miles, where the OEM rotors went over 200K. They warped, squeaked, and had pedal vibration. I now scrounge pick-a-part for OEM rotors that are still within service life limits for thickness, and use them.
As far as my C4, it has all 4 born-with rotors and pads. I just inspected the pads. At 42K miles, I have 50% remaining on the front, and over 50% remaining on the rears. If the annual mileage averages the same for the next 27 years as it has for the first 27 years, my C4 will still have its original Bowling Green installed pads and rotors long after I'm dead and buried. I'm not going to change something that works just fine, and has for 27 years.
I realize you may not have serviceable OEM brakes, and need replacement components. I'm just pointing out that I feel fortunate I don't have to come up with replacements. Because I don't, I'm no help in sourcing C4 brakes. But my experience with overseas brake components has been dismal. Good Luck
