When it comes to rotors, many people have a difficult time deciding whether slotted or drilled are the better option. Slotted rotors offer superior performance and longer life than their drilled counterparts. This is because slots help to remove any gases or debris that may build up on the surface of the rotor, allowing for improved braking power and reduced brake fade due to excessive heat buildup. Additionally, slotting also helps keep brakes cleaner by dispersing moisture from water and other liquids away from rotor surfaces. On the flip side, drilling can reduce vehicle weight by creating lighter-weight rotors that require less energy to move around during stopping maneuvers. Drilled holes also allow air into the disc surface which further aids in cooling as well as helping clear dust particles more easily than with solid discs without holes. Ultimately though, it really depends on your needs; if you're looking for superior braking performance then slotted rotors are often preferred but if weight reduction is more important then you might benefit more from drilled options instead!
