What is the benefit of a drilled brake rotor?

Drilled rotors have holes that help to vent heat and moisture away from the braking surface. This can lead to improved and more consistent braking performance, especially under heavy use.

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 does the black finish do?

The black finish on this rotor is primarily for corrosion resistance during shipping and storage. It helps prevent rust from forming on the rotor surface before installation.

About this part

Product Details

This is the R1 Concepts rear left drilled brake rotor for your 1988-1990 BMW 325iX. It's designed to replace the original rotor on the driver's side rear wheel. Drilled rotors like this one help dissipate heat and gasses more effectively than standard solid rotors, which can lead to more consistent braking performance, especially during repeated stops.

The rotor features a black finish, which helps protect it from rust and corrosion during storage and transit. The drilling pattern is specifically laid out to help vent heat and moisture away from the braking surface. This rotor is a direct replacement for the factory part, meaning it should fit right onto your existing brake setup without modification.
