What is the benefit of drilled and slotted rotors?

Drilled holes help to vent heat and moisture away from the rotor surface, which can improve cooling. The slots help to sweep away brake dust and gases, which can maintain a more consistent grip between the pad and rotor.

Does this rotor come with any hardware?

This product is for the brake rotor only. Installation hardware, such as lug nuts or brake pads, is sold separately.

What is the black coating on the rotor?

The black electro-coating is a protective finish applied to the rotor surface. It helps prevent rust and corrosion, especially during storage and initial installation, while also providing a clean appearance.

About this part

Product Details

This rear left brake rotor features a black electro-coating and a combination of drilling and slotting. The drilling helps dissipate heat and moisture, while the slots help clear away brake dust and gas. This updated design can lead to more consistent stopping power, especially during repeated hard braking.

Built from a durable cast iron, this rotor is designed to meet the demands of daily driving. The black electro-coating not only gives it a clean look but also helps protect against rust and corrosion, which is especially important for components exposed to the elements. This rotor is a direct replacement for your original equipment, meaning it fits right without modification.
