DFC 12-21 BMW 330i Front Hi-Carbon Alloy Geomet Coated Rotor - Dimpled and Slotted

Starting with a maximum lateral runout of just 0.050 MM, these DFC rotors are built to keep things smooth. They use a hi-carbon alloy iron casting, which is a well-built material that helps with stability and durability. The vane configuration is designed to match the original equipment on many BMW models, ensuring that heat dissipates properly to keep your brakes working well under pressure. Plus, they're precision mill-balanced to avoid vibrations when you're stopping.

The dimpled and slotted design on these rotors isn't just for looks; the slots help clear out gas and dust that can build up between the pad and rotor, giving you a more consistent feel. The dimples help with heat management too. DFC coats these rotors with Geomet to protect them from rust, which is a big help during storage and initial installation. The fine-turned finish, at 16 RMS, helps the new brake pads bed in nicely for improved initial performance.

This rotor is a solid option for a range of BMW vehicles, including models like the 330i, 428i, and M240i. It's a good idea to check the full fitment list to make sure it's the right part for your specific car.
