Dynamic Friction 4804-31009 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4804-31009 is a GeoSpec® fully coated plain disc brake rotor engineered as a direct OE replacement. Featuring DFC's proprietary GeoSpec® silver-gray rust-prevention coating applied inside and out, this rotor delivers superior corrosion resistance compared to conventional paint or zinc coatings — and requires zero pre-installation cleaning or degreasing.

Key Features:

• GeoSpec® Full Coating: Patented silver-gray finish protects the entire rotor surface — inside and out — from rust and corrosion far better than standard zinc or painted finishes
• Premium G3000/G11H18 Iron Casting: Engineered for strength, stability, and long-term durability
• OE Vane Configuration: Original equipment vane geometry ensures proper and maximum heat dissipation during braking
• CNC-Machined to Tight Tolerances: Precision machining ensures accurate fit and consistent performance
• 100% Mill-Balanced: Every vented rotor is electronically mill-balanced for smooth, vibration-free stops at any speed
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in and quieter stops
• Ready to Install: No degreasing or additional preparation required — saves time during installation
• Direct OEM Replacement: Designed to match the same form, fit, and function as the original equipment rotor with no modifications required
• Plain / Smooth Style: Solid smooth rotor surface for everyday street and commute driving
• 1-Year Warranty: Backed by Dynamic Friction Company against manufacturer defects
