R1 13-21 BMW 230i Rear Right Drilled Black Brake Rotor

These R1 Concepts rear brake rotors feature drilled holes, a design choice that helps manage heat buildup during braking. This can lead to more consistent stopping performance, especially under repeated braking conditions. They are made from a solid cast iron material, which is a common and reliable choice for brake rotors due to its thermal properties and durability.

The drilled holes on this rotor serve a specific purpose: they allow gases and heat generated by the brake pads to escape more freely. This helps prevent the rotor surface from getting too hot, which can cause brake fade. The solid rotor design means it's a single piece of cast iron, making it a straightforward replacement for your original equipment rotor. This rotor is specifically for the rear right side of your vehicle.
