The answer to your first question is torque. With a larger rotor the braking force is applied further from the center of rotation which increases the braking torque being applied to the wheels. There is also a cooling benefit as the larger rotor has more mass to absorb the heat of braking friction, more cooling vents around its perimeter to dissipate the heat, and a longer time interval before the same pad area comes beneath the pad to be reheated by the friction.
You would new calipers to allow fitment of larger pads, and remachined rotors to have the correct surface finish on the new larger pad swept area. Check sources such as Wilwood if you really want an all new braking system for your car. Plus, you may find you would need very short life track tires to allow full use of the increased braking force without the tires losing grip with the road.
