M/M and A/M and S/M all have the same hydraulics
so yes
W? 911 A/M calipers the pedal ratios are
stock 19.05mm 41.311
20.5mm 35.674
20.64 mm 35.192
22.2 mm 30.42
23.8mm 26.467 Recommended for experienced hardcore track use only
each increase in m/c size is incrementally better,
the def. of better here is higher and firmer requiring more leg
