      c4 big brake upgrades

      What are my options for upgrading the factory brakes on the c4 front and rear suspension?I'm putting the whole setup in my '70 RS and I would like to upgrade the brakes.I also would like to run two master cylinders and woul like to know what size m/c bore for the front and for the back depending on what caliper options I have.I'd rather not get into the big rotor vs. little rotor debate.I would prefer 13" in front and at least 12" in the rear.So what you guys suggest?
