What is the main benefit of a drilled brake rotor?

Drilled rotors have holes that allow heat and gases to escape from the braking surface. This helps prevent brake fade and keeps stopping power more consistent, especially during heavy or repeated braking.

Does this rotor come with any hardware?

This product listing is for a single rear left brake rotor only. Any necessary mounting hardware, such as caliper bolts or brake pads, would need to be purchased separately.

How do I maintain the black finish on this rotor?

The black finish is primarily for corrosion resistance during storage and initial use. During normal operation, brake dust and friction will wear away the finish on the braking surface. Regular cleaning of your wheels will help maintain the appearance of the rotor.

About this part

Product Details

This listing is for one R1 Concepts 623-46003L rear left drilled brake rotor, designed for 1986-1992 Buick ALLANTE models. The rotor features a black finish and drilled holes, which help to vent gases and heat away from the braking surface.

Drilled rotors like this one are a good choice if you're looking for improved performance over standard, plain rotors, especially during repeated braking events. The holes allow hot gases and dust to escape, which helps prevent the rotor surface from getting too hot and losing effectiveness. This can lead to a more consistent feel at the pedal, even when you're braking hard or frequently. The black finish not only looks sharp but also helps protect the rotor from rust during shipping and storage.
