This is a set of brakes I made for my 1/24 Ferrari 360.
The rotors were turned on the late to shape, and then the cross drilled holes were drilled with the part on the rotary table and a sensitive drilling attachment holding a #80 bit. Each rotor has 70 holes. I drilled the rotors two at a time (left side and right side) using the kit part as a pattern reference. The center hub was cut hollow in the back to hold the poly caps to retain the wheels. The brakes were made as a direct replacement for the kit parts, and fit on with no additional modifications.
