The DFC Geomet-coated rotor is a hi-carbon alloy replacement for 2016–2019 Cadillac ATS left-front applications, offering reliable braking with an OE vane configuration to aid heat dissipation. Geomet corrosion protection preserves the rotor finish while precision mill-balancing and a fine-turned 16 RMS surface reduce vibration and promote better initial pad bedding. Cast from G3000/G11H18 iron with controlled DTV (0.10 mm) and lateral runout (0.50 mm).
