What is the benefit of drilled brake rotors?

The drilled holes on this rotor help to vent hot gases and heat away from the braking surface. This can lead to more consistent braking performance, especially during repeated stops or spirited driving.

Does this rotor come with hardware?

This product listing is for the brake rotor only. It does not include installation hardware, which should be checked against the manufacturer's recommendations for your specific vehicle.

What is the black coating on the rotor for?

The black coating is a protective finish applied to the rotor to prevent rust and corrosion. It also provides a clean appearance before installation and helps protect the rotor during shipping.

About this part

Product Details

The drilled holes on this R1 Concepts rotor are specifically designed to help vent hot gases and heat away from the braking surface. This is especially important for a performance-oriented car like the 1991-1993 BMW M5, where braking performance needs to stay consistent even under demanding use.

This rotor is built from a strong cast iron material, which is a standard for good reason in brake components. The black coating applied to the rotor not only gives it a clean look but also helps protect it from rust and corrosion, particularly during shipping and initial installation before the brake pads seat properly. It's a direct replacement for your original left-side front rotor, meaning it fits right onto your existing hub assembly without needing modifications.

When you're replacing your rotors, it's always a good idea to inspect your brake pads and consider replacing them at the same time if they're worn. This ensures you get the best possible braking performance and longevity out of your new components.
