The first drilled and slotted rotors were made of cast iron, but with technological advancements, they are now made of more efficient materials such as carbon-ceramic, composites, and aluminum. Initially, they were primarily used in high-performance and racing vehicles.īut now, they are used in many vehicles as they have been proven to improve braking performance. This can help dissipate heat more efficiently and provide better braking performance.ĭrilled and slotted rotors have been around for a while, but they have become increasingly popular recently.
The rotors have holes and slots drilled into them, which provide increased surface area and improved ventilation for the rotor. Drilled and slotted rotors are a type of brake rotor that is designed to improve the vehicle’s braking performance.
