What Are Slots in Rotors For?

Slotting in rotors means that the rotor has a number of slots machined into it. These slots can vary in size, but they typically have a width similar to that of the bolt that holds the rotor on the hub.

The purpose of slots in rotors is to help the rotor spin more smoothly. When the rotor spins, it creates a centrifugal force. This force is directed outward and tries to pull the hub and the rest of the rotors away from each other.

The slots in a rotor act as an interface between the centrifugal force and the hub, allowing them to move more freely. This allows for a smoother rotation and reduces friction, which can lead to improved fuel efficiency.
