Dynamic Friction 4802-40037 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4802-40037 GeoSpec Coated Brake Rotor is a plain, smooth-faced disc brake rotor engineered to deliver OEM-quality stopping performance with outstanding corrosion resistance. Part of DFC's GeoSpec coated rotor program, this rotor features a proprietary silver-gray coating that outperforms conventional zinc plating and paint-based finishes in rust and corrosion protection.

Each GeoSpec rotor arrives processed dry, shipped dry, and ready to install — no cleaning or prep work required before mounting. The coating is safely swept away during normal brake pad bed-in, leaving no harmful residue on the friction surfaces.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and long-term durability
• GeoSpec proprietary coating provides superior corrosion protection over zinc plating and conventional paint
• OE vane configuration ensures proper airflow and maximum heat dissipation
• CNC-machined to tight tolerances for consistent, precise fitment
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• 100% precision mill-balanced for smooth, vibration-free braking at any speed
• 100% inspected at final QC station to verify all critical OE specifications are met
• Plain/blank rotor surface — no slots or cross-drilling
• Direct OEM replacement — no modification required

The DFC GeoSpec program covers more than 1,400 SKUs across a wide range of domestic and import passenger cars and light trucks. This rotor is backed by Dynamic Friction Company's manufacturer warranty against defects.
