R1 11-18 BMW X3 Rear Left Drilled Black Brake Rotor

This rear left brake rotor from R1 Concepts features a black electro-coating, a finish that helps prevent rust and corrosion, especially around the hub and edges. It's a drilled rotor, meaning it has holes drilled through the braking surface. These holes help dissipate heat and gases that build up during braking, which can improve stopping performance and reduce the chance of brake fade, particularly during spirited driving or repeated stops.

Designed as a direct replacement for the original rotor on your 2011-2018 BMW X3, this part is specific to the rear left position. The drilled pattern offers a functional benefit by allowing heat and brake dust to escape the rotor surface more easily. This can lead to more consistent braking performance and a cleaner look over time compared to a standard solid rotor. It's a well-built component intended to restore your vehicle's braking capability.
