Dynamic Friction 4802-40033 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4802-40033 GeoSpec Coated Brake Rotor is a plain-style, fully coated disc brake rotor engineered to deliver OE-quality stopping performance with superior corrosion protection. GeoSpec's patented silver-gray coating is applied to the entire rotor — inside and out — fighting rust far more effectively than conventional paint or zinc coatings, and it requires no cleaning or degreasing prior to installation.

Each rotor is CNC-machined at state-of-the-art facilities to the tightest tolerances in the industry. A non-directional surface finish promotes a faster, more even brake pad bed-in for quieter, smoother stops from day one. All vented rotors undergo 100% electronic mill-balance inspection to eliminate vibration at any speed and ensure every unit meets OE specifications before it ships.

Key Features:

• Full GeoSpec Coating: Patented silver-gray finish applied completely inside and out for superior rust and corrosion resistance over zinc or conventional paint
• Premium G3000/G11H18 Iron Casting: Provides the strength, stability, and durability needed to meet or exceed OEM standards
• OE Vane Configuration: Matches original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances: Precision machining ensures consistent rotor thickness and surface flatness
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in for quieter and smoother stops
• 100% Mill-Balanced: Electronically balanced for vibration-free performance at all speeds
• Ready to Install: No pre-degreasing or additional preparation needed — saves time and labor during installation
• Meets OE Specifications: Each rotor passes a full 100% inspection of all critical attributes before shipping

The DFC 4802-40033 is part of the GEO-KIT 4000 series, sold as a single rotor replacement. It is designed as a direct OEM replacement, requiring no modifications, and is suitable for normal commute, performance street, and light towing applications.
