What is the benefit of the black coating on this rotor?

The black electro-coating is applied to the non-friction surfaces of the rotor. Its main purpose is to prevent rust and corrosion, helping your rotors look better for longer, especially in areas exposed to moisture.

Do I need to buy two of these rotors for my car?

Yes, brake rotors are typically installed in pairs on the same axle. This listing is for a single rear left rotor, so you will need to purchase two to replace both rear rotors on your vehicle.

How do the drilled holes and slots help my brakes?

The drilled holes allow hot gases and heat generated during braking to escape from the rotor surface. The slots help to sweep away dust and debris, keeping the brake pad surface clean. Together, they help reduce brake fade and improve stopping consistency.

Product Details

This rear left brake rotor from R1 Concepts features a black electro-coating, which helps prevent rust and corrosion, especially on the non-friction surfaces. It's drilled and slotted, a design choice that helps to vent gases and heat away from the pad surface. This means you get more consistent braking performance, particularly when you're stopping hard or repeatedly.

Built for a range of Mercedes-Benz models like the CLS450, E400, and E43 AMG, this rotor is a solid option if you're looking to replace worn-out factory rotors. The drilled holes help with initial bite and gas release, while the slots keep the pad surface clean and cool. This combination helps reduce brake fade and can extend the life of your brake pads by keeping them working more efficiently.

This rotor is sold individually, so be sure to order two if you need to replace both sides on your vehicle. It's designed to fit right in place of your original equipment rotor, making installation straightforward.
