Hello forum members. I am on the next step in my build which is having brake rotor hats and caliper brackets made for my car. I have my wheels and their measurements. I have the uprights, their mounting ears and the hubs contained within them and their associated measurements. I also have the brake rotors. The issue I'm having is that the dimensions the fabricator is asking for I cannot give based on what I have here physically. In order to make the rotor hats, he needs proper offset numbers but to give him proper offset numbers I need the measurements for backspacing of the calipers which is based on the brackets, which I don't have either.
So my question is this: should I come up with an arbitrary number for one so it will dictate the measurement of the other, or is the offset of the brake rotor based on particular parameters? What is the proper way to judge how the caliper and rotor fits inside the wheel axially? I am trying to measure two items that are in space and I don't know where to start. Thanks in advance.
