The DFC Geomet-coated front drilled rotor for 2020–2026 Mercedes-Benz GLS450 is a hi-carbon alloy direct-fit replacement designed to restore front braking with drilled ventilation for heat relief. Constructed from G3000/G11H18 iron castings and OE-style vanes for efficient heat management, the rotor is precision mill-balanced, fine-turned to a 16 RMS finish to aid pad break-in, and Geomet-coated for corrosion resistance. DTV ≤0.10 mm; lateral runout ≤0.50 mm.
