What is the purpose of the drilled holes on this brake rotor?

The drilled holes help to vent hot gases and brake dust away from the rotor surface. This can improve braking performance, especially during repeated stops, and help reduce brake fade.

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

The black coating is primarily for appearance and corrosion resistance during shipping and storage. It helps prevent surface rust from forming before the brake pads are installed and bedded in.

Does this rotor come with any hardware?

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

About this part

Product Details

This listing is for one R1 Concepts rear right drilled black brake rotor, part number 623-80020R, designed for the 1988 and 1989 Mazda 929. This rotor features a black coating to help prevent rust and corrosion, especially during storage or initial installation, and has drilled holes that help dissipate heat and gas from the braking surface.

The drilled holes on this rotor are a common feature for improved braking performance, particularly in wet conditions or during repeated hard stops. They allow brake dust and heat to escape the rotor surface more effectively, which can lead to more consistent stopping power and a reduction in brake fade. The black coating is a practical touch that makes the rotor look good right out of the box and offers some protection against surface rust before the brake pads bed in.
