How many brake rotors are included in this purchase?

This listing is for a single rear right brake rotor. If you need to replace both rear rotors, you will need to purchase two units.

What is the benefit of drilled and slotted rotors compared to standard rotors?

Drilled holes help to vent heat and moisture away from the rotor surface, which can prevent brake fade. The slots help to sweep away brake dust and gases, ensuring a cleaner contact patch between the rotor and pads for more consistent braking performance.

Does this rotor come with any hardware for installation?

This product listing is for the brake rotor only. Installation hardware, such as lug nuts or brake pad hardware, is typically sold separately. Refer to the manufacturer's installation instructions for a complete list of required components.

About this part

Product Details

This listing is for one rear right brake rotor designed for your 2003-2005 BMW Z4. It's a drilled and slotted rotor with a black finish, intended to replace the stock rotor on the passenger side rear wheel. The drilled holes help dissipate heat and moisture, while the slots help clear away brake dust and gas, which can improve braking consistency, especially during harder stops.

R1 Concepts uses a well-built iron casting for these rotors, which is then treated with a black finish. This finish not only gives the rotor a distinct look but also helps protect it from rust and corrosion, particularly in areas where road salt is used. The combination of drilled holes and slots means you get a rotor that performs better than a plain blank rotor, offering a solid option for drivers looking for improved stopping power and a cleaner appearance.

When installing, remember this is for the rear right side only. It's a direct replacement for your factory rotor, so no modifications are needed for installation. Make sure to check your other brake components, like the brake pads, to ensure they are in good condition as well.
