What is the main benefit of a drilled brake rotor?

Drilled rotors have holes that allow heat and brake dust to escape from the surface. This helps prevent brake fade and maintain consistent stopping power, especially during repeated braking.

Does this rotor come with any hardware?

This listing is for the brake rotor only. You will need to reuse your existing hardware or purchase new hardware separately.

What is the black finish on the rotor for?

The black finish is applied for corrosion resistance. It helps protect the rotor from rust and environmental damage, keeping it looking good and performing well.

About this part

Product Details

This R1 Concepts brake rotor features a drilled surface, a design choice that helps dissipate heat and gasses more effectively than a standard smooth rotor. It's made to fit the rear right side of your 1988 through 1994 Buick Cutlass Supreme, offering a direct replacement for your original part.

The drilled holes in this rotor serve a practical purpose during braking. They allow hot gases and dust generated by the brake pads to escape from the rotor surface. This helps maintain consistent contact between the pad and rotor, which can lead to improved braking performance, especially under heavier use. The black finish on the rotor is primarily for corrosion resistance, helping it look good and last longer, even in damp conditions.
