What is the benefit of drilled and slotted brake rotors?

Drilled holes help to vent heat away from the rotor surface, while the slots help to wipe away brake dust and gasses. This combination can lead to improved stopping power and more consistent performance, especially under heavy braking.

Does this rotor come with hardware?

This product includes one rear right brake rotor. Brake hardware, such as mounting bolts or clips, is typically sold separately. Please check the product details or contact us if you need specific hardware.

Should I replace my brake pads when installing new rotors?

It is highly recommended to replace your brake pads when installing new rotors. New pads paired with new rotors will ensure optimal braking performance and help prevent premature wear on your new components.

Product Details

In this box, you get one R1 Concepts rear right drilled and slotted brake rotor, part number ECB-31030R. This rotor is designed to fit a variety of BMW vehicles, including models like the 1995-2001 740i, the 1994-1997 840Ci, and the 1993-1997 850Ci.

The combination of drilled holes and deep slots on this rotor helps to dissipate heat and gasses more effectively than a standard rotor. The drilled holes allow heat to escape, while the slots help to wipe away dust and water from the pad surface. This means you get more consistent braking performance, especially during hard stops or in wet conditions. The black finish not only looks good but also helps to prevent rust on the non-friction surfaces.

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