DFC 14-21 Mercedes-Benz S550 Rear Drilled Hi-Carbon Alloy Geomet Coated Rotor

Starting with a G3000/G11H18 iron casting, this DFC rear brake rotor is built for strength and stability. The iron composition helps ensure durability, while the original equipment vane configuration is key for dissipating heat effectively. This is important because too much heat can cause brake fade, meaning your brakes won't work as well when you need them most.

You'll notice a smoother stopping experience thanks to the 100% precision mill-balancing. This process eliminates vibrations, so you get a more comfortable ride. The rotor also features a fined turned finish, aiming for a 16 RMS surface roughness. This helps the new brake pads seat properly during the initial break-in period, leading to better performance right away. Plus, the Geomet coating offers solid corrosion protection, keeping the rotor looking good and functioning well even in tough conditions. With a maximum disc thickness variation of just 0.010 MM and lateral runout of 0.050 MM, these rotors are made to close tolerances for consistent performance.
