The DFC Geomet-coated front rotor for 2011–2018 BMW X4 is a hi-carbon alloy replacement that restores braking feel and combats corrosion. Manufactured from premium G3000/G11H18 iron castings with OE vane geometry for improved heat dissipation, it’s precision mill-balanced and fine-turned (16 RMS) to minimize vibration and support pad break-in. Geomet surface protection plus DTV ≤0.10 mm and lateral runout ≤0.50 mm maintain consistent stopping performance.
