Dynamic Friction 940-31196D DFC Geomet Dimpled Slotted Brake Rotor

The Dynamic Friction Company (DFC) 940-31196D is a premium GeoMet dimpled and slotted brake rotor engineered for drivers who demand superior stopping performance and long-lasting durability. Combining an advanced surface treatment with an aggressive rotor face design, this rotor delivers consistent, fade-resistant braking in both everyday driving and high-demand conditions.

GeoMet Coating Technology:

DFC's proprietary GeoMet coating is a zinc-based, chrome-free inorganic surface treatment applied to the entire rotor — including the hat, vanes, and edges. This corrosion-resistant finish dramatically extends rotor life by preventing rust and oxidation, maintaining a clean appearance throughout the rotor's service life without the unsightly rust streaking common on untreated rotors.

Key Features:

• Dimpled & Slotted Design — Drilled-style dimples and precision-machined slots work together to evacuate heat, gas, and brake dust from the rotor surface, improving bite and reducing brake fade under repeated hard stops
• GeoMet Anti-Corrosion Coating — Full-coverage zinc-based coating resists rust and oxidation across the entire rotor surface, including vented channels and hat area
• G3000 Metallurgy — Cast from high-carbon G3000 grade iron for superior thermal conductivity, noise reduction, and extended wear life compared to standard cast iron rotors
• Precision Machined — CNC-machined to strict OE tolerances for minimal runout, vibration-free operation, and a direct OEM replacement fit
• Fully Assembled & Ready to Install — No additional prep required; rotor arrives with protective coating pre-applied

The Dynamic Friction 940-31196D is an ideal upgrade for performance-minded drivers seeking a direct-fit replacement rotor with enhanced thermal management and corrosion protection over standard OE-style rotors.
