What is the main benefit of drilled brake rotors?

Drilled brake rotors have holes that help to dissipate heat and gases away from the braking surface. This can lead to improved stopping performance and help reduce brake fade, especially during repeated hard braking.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Any necessary installation hardware, such as lug nuts or brake pads, would need to be purchased separately.

What is the black finish on the rotor for?

The black finish on the rotor is primarily for corrosion resistance. It helps protect the rotor from rust during shipping and storage, and it also gives the rotor a clean look.

About this part

Product Details

This listing is for one (1) R1 Concepts 623-80018L front left drilled brake rotor. It's designed for the 1988 through 1991 Mazda 929. The drilled holes in this rotor help to vent gases and heat away from the braking surface, which can lead to more consistent stopping power, especially during repeated hard braking.

The rotor features a black finish, which helps protect it from rust and corrosion during storage and transit. While it's a direct replacement for your stock rotor, the drilled pattern offers an advantage over plain rotors by allowing heat and brake dust to escape more easily. This can help prevent brake fade and keep your braking performance more reliable.
