DFC 21-25 BMW M4 Left Front Drilled Hi-Carbon Alloy GEOMET Coated Rotor

If you're working on a 2021-2025 BMW M3, M4, or M2, this left front brake rotor from DFC is a solid option for replacing worn-out parts. It's built with G3000/G11H18 iron castings, which are known for being strong and stable, helping to dissipate heat effectively thanks to its original equipment vane configuration. This is important for keeping your brakes working consistently, especially during spirited driving.

DFC precision mill-balances each rotor to ensure you get smooth stopping power without any unwanted vibrations, even at higher speeds. The fine-turned finish, measuring 16 RMS, helps the new rotor and your brake pads break in together properly for improved initial performance. Plus, the GEOMET coating offers strong protection against corrosion, keeping your rotors looking good and performing well over time. This rotor is designed with a maximum lateral runout of 0.050 MM and a maximum disc thickness variation of 0.010 MM, ensuring it spins true and stops smoothly.
