DFC 20-25 BMW Alpina XB7 Front Hi-Carbon Alloy Geomet Coated Rotor

When it’s time to replace the front brake rotors on your BMW Alpina XB7, or other compatible BMW models, DFC offers a solid option with their 900-31191 rotor. This rotor is built using G3000/G11H18 iron castings, which are known for their strength and stability, helping to ensure consistent performance and durability. The vane configuration is designed to match the original equipment, which is crucial for dissipating heat effectively and preventing brake fade during demanding stops.

You can expect a smoother driving experience because each rotor is precision mill-balanced to eliminate vibration. The fine-turned finish, measured at 16 RMS, helps the new pads and rotor bed in together properly for improved initial braking. Plus, the Geomet coating provides a high level of corrosion protection, keeping your rotors looking good and functioning well, even in harsh weather conditions. The lateral runout is kept to a maximum of 0.050 MM and disc thickness variation to 0.010 MM, ensuring a stable and reliable braking surface.

This rotor is designed to fit a range of BMW vehicles, including models like the 740i xDrive, 750i xDrive, and the Alpina B8 Gran Coupe, in addition to the Alpina XB7. It’s a direct replacement part, meaning it fits right without needing modifications.
