BMW M240i xDrive Brake Rotors (2) - Front - DBA - 5000 Series HD - `18-`20. Direct-replacement, composite two-piece front rotors engineered by DBA for the 2018–2020 M240i xDrive (370mm front rotor). Designed for drivers who want the performance benefits of a 5000 Series rotor with a smooth OE-style finish.

The DBA 5000 Series HD combines high-carbon cast-iron rings with aerospace-grade T6061-T6 aluminum hats, joined using National Aerospace Standards (NAS) bolts and crimp nuts. This construction reduces unsprung weight, manages heat transfer more effectively than one-piece castings, and permits uniform radial disc expansion through the cast-iron rings. The HD variant provides a smooth, OE-style surface for drivers who prefer no slots, cross-drilling, or dimpling. DBA offers both complete assemblies (hats and rings bolted together) and replacement rings or hats to support long-term serviceability.
