What is the benefit of drilled and slotted rotors?

Drilled holes help to vent heat and gases away from the pad surface, reducing brake fade. The slots help to sweep away dust and moisture, keeping the braking surface clean for more consistent grip.

Does this rotor come with any hardware?

This product includes the brake rotor only. You will need to reuse your existing brake hardware or purchase it separately.

What is the black finish on the rotor for?

The black finish is applied to the non-friction surfaces of the rotor. It helps to prevent rust during shipping and storage, and also gives the rotor a cleaner look once installed.

Product Details

This is a rear left drilled and slotted brake rotor from R1 Concepts, made to fit your 1981-1984 BMW 733i. If you're looking to get more consistent stopping power, especially during repeated hard braking, rotors with drilled holes and slots can make a notable difference. The drilled holes help to vent heat and gases away from the pad surface, while the slots help to sweep away dust and moisture. This helps keep the braking surface clean and ready to grab, reducing the chance of fade.

This rotor is finished in black, which not only looks good but also helps to prevent rust on the non-friction surfaces during storage and transit. It's a well-built component designed to work with your vehicle's existing brake system. The combination of drilled holes and slots is a popular choice for drivers who want a bit more confidence in their braking, whether it's for daily driving or more spirited use.
