What is the benefit of drilled brake rotors?

Drilled rotors have holes that help to vent heat and gases away from the brake pad surface. This can lead to more consistent braking performance, especially during repeated stops or heavy braking situations.

What does the black E-coating do?

The black E-coating is applied to the non-friction surfaces of the rotor to prevent rust and corrosion. This helps the rotor maintain its appearance and function over time.

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 is a rear right drilled black brake rotor from R1 Concepts, made specifically for the 1986 through 1992 Buick Allante. This rotor is designed to replace your stock rear right rotor, helping to restore your braking performance. The drilled pattern on the rotor surface helps to dissipate heat and gases that build up during braking, which can improve stopping consistency, especially under heavier use.

R1 Concepts uses a black E-coating on this rotor to protect it from rust and corrosion, keeping it looking good and functioning properly for longer. This coating is applied to the non-friction surfaces of the rotor. The drilled holes are precision-machined to help reduce brake noise and improve the rotor's ability to shed heat and moisture.
