The DFC Geomet-coated left-front rotor for 2016–2018 BMW X4 is a hi-carbon alloy replacement that restores braking performance and provides corrosion protection. It features premium G3000/G11H18 iron castings and OE-style vanes to enhance heat dissipation, plus precision mill-balancing and a fine-turned 16 RMS finish to reduce vibration and aid pad break-in. Geomet coating defends against corrosion; DTV ≤0.10 mm and lateral runout ≤0.50 mm ensure smooth operation.
