Master cylinder question

[GallopinGhost]

I just bought a new strange MC. Their recommendation is with 4 wheel disks, use a 1.125 bore and with 2 wheel disk, 2 wheel drum to use a 1.032 bore. I can say, without even bleeding the lines the pedal feels good, better than the mopar aluminum one I had on
