Dynamic Friction 4812-03052 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4812-03052 GeoSpec Coated Plain Brake Rotor is a premium OE-replacement disc brake rotor engineered for reliable, quiet, and long-lasting stopping performance. Featuring DFC's signature GeoSpec® corrosion-resistant coating, this rotor arrives with a durable silver-gray finish that outperforms conventional paint or zinc coatings in rust prevention — and requires zero pre-installation cleaning.

Key Features:

• GeoSpec® Full Coating: Completely coated inside and out with a patented rust-prevention paint; processed dry, shipped dry, and ready to install right out of the box
• Premium G3000/G11H18 Cast Iron Construction: Engineered for superior strength, stability, and long-term durability
• OE Vane Configuration: Duplicates original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances: Ensures precise fit and consistent braking performance
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in for quieter and smoother stops
• 100% Mill-Balanced: Electronically inspected and corrected for balance to eliminate vibration at any speed
• Plain / Smooth Rotor Surface: Ideal for OE replacement and everyday street driving
• Solid Rotor Design: 302 mm outside diameter, 10 mm nominal thickness, 5-lug bolt pattern (114.3 mm bolt circle)

The DFC GeoSpec® coating is designed not to contaminate friction or rotor surfaces, ensuring a proper brake pad bed-in process and consistent wear characteristics from the first stop. Each rotor passes a 100% final inspection station to verify all critical attributes meet OE specifications before leaving the facility.
