Drilled and slotted rotor direction. 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. The holes in the rotor help to get rid of excess water in the rotor when driving in the rain. But here is what we recommend. Drilled and slotted rotors offer drivers the consistent performance they want without changing the responsiveness of the brake pedal.

Luckily if your rotors are not labeled there is an easy way to tell.
List of the cons of drilled and slotted rotors. For slotted rotors with straight internal cooling vanes the direction of the slots is totally up to you and what you think looks best. Slotted rotors have more metal than a drilled rotor. They sometimes experience premature wear. 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. This process gives you the confidence needed as a driver that you can handle whatever situation might come your way.
Only in the case of straight vane or solid rotors if a customer prefers the appearance rotors may be. 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.
