The R1 Concepts Geo-Carbon drilled-and-slotted rotor for 2006–2015 BMW 328i xDrive (rear right) is made for that rear-right all-wheel-drive application. The drilled and slotted braking face supports heat dissipation and pad material removal, helping restore consistent pad contact when replacing a worn rear rotor. This rotor is intended as a replacement for the specified 328i xDrive models.
