What is the main benefit of drilled brake rotors?

Drilled rotors help to vent hot gases and moisture away from the brake pad surface. This can lead to more consistent stopping power and help reduce brake fade, especially during repeated hard braking.

What material are these rotors made from?

These rotors are constructed from solid cast iron, a common and well-built material known for its durability and heat handling capabilities in braking systems.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Installation hardware, such as lug nuts or brake pads, is typically sold separately.

About this part

Product Details

These R1 Concepts drilled rotors are made from a solid cast iron, a well-built material that offers good heat dissipation for consistent braking. The drilling pattern on this rear right rotor helps to vent gases and moisture away from the pad surface, which can improve stopping power, especially during repeated hard braking. This rotor is finished in black, giving it a clean look behind your wheels.

Designed as a direct replacement for the rear right side of your 1978-1981 BMW 733i, this rotor aims to restore your braking performance. The drilled holes are precisely placed to help prevent brake fade by allowing heat and gases to escape. This makes them a solid option if you're looking for an improvement over standard, plain rotors.
