Dynamic Friction 9504-31121 DFC GeoMet Dimpled & Slotted Brake Rotor

The Dynamic Friction Company (DFC) 9504-31121 is a premium GeoMet-coated dimpled and slotted brake rotor engineered for drivers who demand superior stopping performance and long-lasting corrosion resistance. The proprietary GeoMet coating provides exceptional rust and corrosion protection across the entire rotor surface—including the hat, vanes, and edges—keeping the rotor looking and performing like new far longer than traditional uncoated or painted rotors.

Key Features:

• GeoMet Coating: Full-surface zinc-and-aluminum flake coating provides outstanding corrosion resistance without affecting braking performance on the friction surface
• Dimpled & Slotted Design: Drilled dimples and machined slots work together to evacuate heat, gas, and debris from the rotor face, improving bite and reducing brake fade under demanding conditions
• Precision Machined: Manufactured to strict OEM dimensional tolerances for a direct-fit, no-modification installation
• Balanced for Smooth Operation: Computer-balanced to minimize vibration and eliminate pedal pulsation
• Enhanced Pad Bite: Slotted channels continuously clean and condition brake pad surfaces for consistent, confident braking response
• Vented Construction: Internal vane venting promotes airflow through the rotor to manage heat during repeated or heavy braking events

Dynamic Friction Company rotors are manufactured using G3000 grade castings and undergo rigorous quality control to meet or exceed OEM specifications. The 9504-31121 is a direct OEM replacement designed for straightforward installation with no drilling, cutting, or modification required. Whether used for daily commuting or spirited driving, this rotor delivers a noticeable upgrade in thermal management and corrosion resistance over standard replacement rotors.
