I'm trying to figure out what size master cylinder to use on my 73 z. I will be using the Arizona z 12.2 4 piston kit for the front and stock z32 rear kit(using the s13 rear irs). I don't want to use a booster and have the option of using either a 7/8 or 1 inch master. I hear pedal effort will be too high for the 1 inch but will the 7/8 be too small for this brake setup?
