In reply to:
A bigger brake will offer more braking torque which will make
that mass more transparent.
More torque for a given pedal force...
But total torque required to lock the wheels is still constant, given the same tire/road surface combination.
Nothing is free. Bigger brakes are a heat management issue, primarily, and part of a "driver feel" issue, and I suppose they look cool, too. The tradeoff is higher unsprung, rotating weight, which is bad, bad, bad. (If I didn't like how my brakes felt, I'd go with better pads, steel lines, and a host of other improvements before I'd add more weight to the hub. Only when the heat becomes a problem would I consider up-sizing.)
Pretty much unless you do track time with the car, or drive downhill riding the brakes, you don't "need" bigger ones.
MHO.
