R1 Concepts GEO-Carbon drilled and slotted rotor set for front fitment on BMW 230i (2007–2021). The carbon-coated, drilled-and-slotted design targets improved braking over OE by enhancing pad bite and ventilation while serving as a wear indicator. Constructed to OEM specifications from G3000-grade cast iron, these mill-balanced rotors include rust protection, countersunk holes to limit cracking and arrive as a two-rotor kit.
