What is the main benefit of drilled and slotted brake rotors?

Drilled and slotted rotors help improve braking performance by allowing heat, dust, and moisture to escape from the rotor surface. This helps prevent brake fade and keeps the pads making better contact with the rotor.

Does this rotor come with any hardware?

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

Product Details

If you're looking to improve your BMW 5 Series' braking performance, especially during spirited driving or heavy use, this rear left drilled and slotted rotor from R1 Concepts is a solid option. It's designed to replace the stock rotor on your 1997-2003 525i, 528i, 530i, or 540i, offering a step up in both looks and function.

The drilled holes help vent hot gases and moisture away from the pad surface, which can lead to more consistent braking, especially under load. The slots also help clear away dust and gas, further improving performance and preventing glazing. The black finish not only looks sharp behind your wheels but also offers some protection against rust. This rotor is a direct replacement, meaning it fits right where your original rotor did, making installation straightforward.
