what a larger rotor does is increase the leverage the caliper has on stopping the car
Right but you will not stop faster, Less pedal pressure,maybe more pedal feel, the contact of the tire with the pavement stops the vehicle directly. The pads on the disk indirectly. More tire on the pavement will stop you faster
If you have heavy crappy wheels with a lot rotating momentum then maybe a little differenvce in stopping distance but with light wheels???/....
I think if you compared a drum brake car with a disk brake car and braked each car from 60 mph that thier would not be much difference in stopping distance providing the same parameters. Only the first time,heat will build quicker in a drum brake car and result in brake fade faster than a disk brake car.
