Dynamic Friction 920-31119DA DFC Geomet Coated Drilled Brake Rotor

The Dynamic Friction Company (DFC) 920-31119DA is a premium drilled brake rotor featuring an advanced Geomet® protective coating for superior corrosion resistance and long-lasting performance. Engineered to meet or exceed OEM specifications, this rotor delivers consistent, reliable stopping power for everyday driving and performance applications alike.

Geomet® Coating Technology:

• Geomet® multi-layer coating provides industry-leading rust and corrosion protection across the entire rotor surface, including the hat, vanes, and edges
• Eliminates unsightly rust bloom that is common on untreated rotors — keeps the rotor looking clean even during break-in
• Coating is zinc and chrome-free, making it an environmentally responsible choice
• Does not require any coating removal before installation — ready to install straight out of the box

Drilled Rotor Design:

• Cross-drilled holes improve heat dissipation, reducing brake fade during repeated or heavy braking
• Drilling pattern helps evacuate gases and debris from the rotor surface for consistent pad contact
• Precision-machined to tight tolerances for minimal runout and smooth, vibration-free braking

Premium Construction:

• Manufactured from high-quality gray iron for durability and thermal stability
• Meets or exceeds original equipment specifications for a direct OEM-style fit
• 100% computer balanced to reduce noise, vibration, and harshness (NVH)
• Each rotor is individually inspected for dimensional accuracy

The Dynamic Friction 920-31119DA is an excellent upgrade or replacement rotor for drivers seeking enhanced corrosion protection and improved brake performance with a clean, finished appearance right out of the box.
