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.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Any necessary installation hardware, such as lug nuts or brake clips, would typically need to be purchased separately.

What is the black finish on the rotor for?

The black finish is a protective coating applied to the rotor's surface. It helps to prevent rust and corrosion during shipping and storage, and can also contribute to the overall appearance of the rotor.

About this part

Product Details

This R1 Concepts drilled brake rotor is made from a durable cast iron that's been finished in black. The drilling pattern on the rotor helps to dissipate heat and gases that build up during braking, which can improve stopping performance, especially under heavy use. It's designed to replace the original rotor on the front left side of your 1984-1991 BMW 318i.

The black finish on this rotor isn't just for looks; it helps to prevent rust and corrosion, keeping the rotor looking good and functioning well over time. This rotor is a direct replacement for your stock part, meaning it fits right into the existing brake system without needing modifications. If you're looking to maintain or slightly improve your BMW's braking capabilities, this rotor is a solid option.
