When less metal is used in the construction of a rotor it has less stopping power than a rotor with more metal content in its construction. They sometimes experience premature wear.
Nakamoto Rear Ceramic Brake Pad Performance Drilled Slotted
Drilled and slotted rotor direction. For slotted rotors with straight internal cooling vanes the direction of the slots is totally up to you and what you think looks best. Slots perform their function identically regardless of direction. Some rodders have correctly stated that the brake rotors surface area is increased by drilling or slotting but the issue in heat transfer is mass not surface area. Drilled and slotted rotors offer drivers the consistent performance they want without changing the responsiveness of the brake pedal. A drilled rotor has less metal content than a slotted rotor. Luckily if your rotors are not labeled there is an easy way to tell.
The problem with regard to our question of drilled and slotted rotors is that those practices act to reduce the mass of the rotor reducing the desired heat transfer. For drilled and slotted rotors it is important to pay attention to which is the left and right rotor. The holes in the rotor help to get rid of excess water in the rotor when driving in the rain. It is not possible to tell if a drilled rotor is installed properly simply by observing the drill pattern. In this case there is no wrong answer. Slotted rotors have more metal than a drilled rotor.
Left side driver side right side passenger side. There is no wrong or right direction when installing your drilledslotted brake rotors. Only in the case of straight vane or solid rotors if a customer prefers the appearance rotors may be. Stoptech sportstop slotted rotors with non directional vanes or solid rotors are marked right or left so as to be consistent with rotors following rules 1 and 2. But here is what we recommend. List of the cons of drilled and slotted rotors.
