What are slotted rotors designed to do?

Slotted rotors are specifically designed to enhance brake performance primarily by addressing heat and gas buildup during braking. When brakes are applied, especially under heavy use or aggressive driving conditions, brake pads can generate a significant amount of heat, which can lead to brake fade and reduced effectiveness. The slots on the rotor serve multiple purposes: they help channel away gases that can become trapped between the brake pad and the rotor surface, thereby maintaining better contact and grip. This improved airflow also assists in dissipating heat more efficiently, allowing the brakes to operate at optimal performance levels for a longer duration.

In addition to this primary function, slotted rotors can contribute to enhanced performance during heavy braking situations, as they provide better traction for the brake pads, leading to more consistent stopping power. While some other options mention potential benefits like a smoother braking surface or aesthetic enhancements, those are not the main design intentions behind slotted rotors. The focus on heat management and gas release is what fundamentally differentiates slotted rotors from standard, solid rotors.
