I am going to use early 4 piston Kelsey Hayes brakes . On the Demon staying 4" small bolt and 15 inch Cragars . On the Barracuda if we do it same brakes but with 68 mustang big bolt 4 1/2" rotors and Torque Thrust wheels. I like the early 4 piston brakes there is no drag when released. Less brake dust. also leaves the wheel base narrow as they came from 67-72
