DFC 13-20 BMW ActiveHybrid 3 Front Hi-Carbon Alloy Geomet Coated Rotor - Dimpled and Slotted

If you're looking to replace the front brake rotors on your BMW 3 Series or 4 Series, this DFC rotor is a solid option. It's built with a hi-carbon alloy and features a dimpled and slotted design, which helps with heat dissipation and pad cleaning. This rotor is designed to fit a range of BMW models, including the 335i, 340i, 435i, and 440i, as well as the ActiveHybrid 3.

DFC uses G3000/G11H18 iron castings for strength and stability, and they've kept the original equipment vane configuration to make sure heat is managed effectively. Each rotor is precision mill-balanced to ensure smooth stopping without any vibration, even when you're braking hard. The fine-turned finish helps your new brake pads bed in properly, and the Geomet coating offers good protection against rust and corrosion, keeping your rotors looking good and performing well.

With a maximum disc thickness variation of just 0.010 MM and lateral runout of 0.050 MM, these rotors are well within spec for a smooth and consistent braking experience. They're a direct replacement for your stock rotors, making installation straightforward.
