BIG front disks (13"+)

what too slow said is true, to a point. the ultimate factor in stopping distance is tire grip. that being said, the way to maximise tire grip during braking is multifold. weight transfer, brake bias, etc all play a factor into this. modulation is also key, which in this discussion is where i will (mostly) stay. with the bigger rotor (all other things being equal), there is better modulation capabilities due to leverage. this is also dependant on brake feel and driver response time (im eliminating ABS as we arent even getting into this). the feel is dependant on the ratios in the caliper bores, and the master sylender, as well as heat dissipation and brake line balooning. the hotter most street pads get, the less they grip. not true when we get into track pads.
so both camps are actually correct. a good driver with skinny, hard tires and smaller rotors can still outbrake a mediocre driver with great tires and pizza sized rotors.

ultimately, i still conclude that the larger rotor and better tire scenario is the way to go, due tpo the best of both worlds.
its been said many times, at may track events, and many autocrosses, that great tires make even a bad car good.

my personal favprite saying is "theres no such thing as too much brake. just not enough tire."
