Dynamic Friction 4812-03049 DFC GeoSpec Coated Plain Disc Brake Rotor Set

The Dynamic Friction Company (DFC) 4812-03049 GeoSpec Coated Plain Disc Brake Rotors deliver OEM-quality braking performance with superior corrosion protection. Engineered as a direct-fit replacement, these smooth-surface rotors are ideal for daily drivers seeking long-lasting, reliable stops.

DFC's proprietary GeoSpec coating forms a durable, attractive silver-gray finish that outperforms conventional paint and zinc coatings in rust and corrosion resistance. Every rotor is processed dry, shipped dry, and ready to install with no pre-degreasing or additional preparation required — saving time and money at installation. The coating is safely swept away by the brake pad friction material during the bed-in process with no harmful effects.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• Full GeoSpec corrosion-resistant coating applied inside and out — withstands 400+ hours of salt spray testing (SAE J2334, GMW 14872)
• OE vane configuration ensures proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available for precise fitment
• 100% precision mill-balanced for smooth, vibration-free stops at any speed
