R1 Concepts GEO-Carbon drilled and slotted rotor set for front fitment on BMW 330i (2016–2025). The carbon-coated, drilled-and-slotted face is intended to increase pad bite and airflow versus OE rotors while acting as a wear indicator. Built from G3000-grade cast iron to OE dimensions, the mill-balanced rotors include rust protection and countersunk holes to minimize cracking; the kit ships as two high-performance replacement rotors.
