smaller brakes and wheels for bigger tires

i want to try to take the classic muscle look even further with 16in wheels and high profile white lettered tires. wondering if anyone could tell me what size rotors and calipers would fit this and possible drop in stopping power. also possibly thinking of going 15s in the front so the ass end is a little higher. this is a daily driver. any and all advice and info welcome.
 
You may need a rear sway bar relocation kit to fit the 16" on the rear as the end of the sway bar may make contact with the wheel. Also you won't need to go 15" up front to have the back sit higher. You can achieve that by having a taller 16" tire in the back than the front. I have 18" wheels front and rear, yet my back tire is 2" taller.
