BMW M240i F23 Brake Rotor (1) - Front - DBA - 5000 Series Slotted Rotor - Silver - `17-`22. A direct-replacement two-piece slotted rotor that combines DBA’s 5000 Series performance technology with reduced unsprung weight for improved heat management and consistent braking feel.

This rotor pairs XG-150 high-carbon cast-iron rings with aerospace-grade aluminum hats (T6061-T6), joined using National Aerospace Standard (NAS) bolts and crimp nuts. The 5000 Series construction reduces heat transfer to the hub while allowing uniform radial disc expansion. The T3 bi-directional slot pattern improves pad bite and gas/contaminant evacuation, making this rotor suitable for spirited street use, track days and club-level competition without changing your hubs or calipers.
