The DFC Geomet-coated left front drilled rotor for 2021–2025 Polestar 2 is a hi-carbon alloy direct-fit replacement that uses drilled faces to aid gas and heat exchange while restoring front braking. Constructed from premium G3000/G11H18 iron castings with OE vane geometry for heat management, the rotor is precision mill-balanced, fine-turned to a 16 RMS finish for break-in, and Geomet-coated for corrosion resistance. DTV ≤0.10 mm; lateral runout ≤0.50 mm.
