The DFC Geomet-coated front brake rotor for 2022–2025 Rivian R1S is a hi-carbon alloy direct-fit replacement that restores factory-style stopping for electric SUV applications. Constructed from G3000/G11H18 iron castings with OE vane geometry for heat dissipation, the rotor is precision mill-balanced to minimize vibration, fine-turned to 16 RMS for improved break-in, and treated with Geomet coating to resist corrosion. DTV ≤0.10 mm; lateral runout ≤0.50 mm.
