Gotta love interchangeable parts
I had the Speedway brake kit on my roadster with Chevy wheels. I wanted to swap wheels from my other car onto the roadster but the wheels are Ford. By swapping rotors I was able to install the Ford wheels on my roadster, saving the cost of new wheels, for nearly the same cost as wheel adapters, but more safely and without adding to the width.
