Dynamic Friction 4002-63118 GeoSpec Coated Drilled & Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4002-63118 GeoSpec Coated Drilled & Slotted Brake Rotor delivers enhanced stopping performance with corrosion-resistant protection for everyday and performance street driving. Engineered as a direct OE replacement, this rotor combines the benefits of cross-drilled holes and precision-cut slots with DFC's proprietary GeoSpec coating for a ready-to-install upgrade over stock rotors.

GeoSpec Coating Technology:

DFC's patented GeoSpec coating forms a durable, attractive silver-gray finish that resists rust and corrosion far better than conventional paint or zinc coatings. Each rotor is processed dry and shipped dry — no cleaning or degreasing required before installation. The coating is safely swept away by the friction material during normal break-in with no harmful effects.

Drilled & Slotted Performance:

• Cross-drilled holes reduce heat buildup on the rotor surface and are chamfered to minimize the potential for cracking
• Precision-cut slots continuously sweep away brake dust, road debris, and gases, preventing pad glazing and maintaining consistent bite
• Combined drill and slot design improves pad-to-rotor grip for shorter stopping distances, especially in wet conditions

Key Features:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• OE vane configuration ensures proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available
• 100% precision cut and mill-balanced for smooth, vibration-free stops at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter performance
• Zinc silver hat finish for additional corrosion resistance
• Vented rotor construction for improved thermal management
• Meets OEM form, fit, and function standards — a true direct replacement

The DFC 4002-63118 is sold as a single rotor. Compatible with a variety of passenger cars and light trucks; confirm fitment prior to purchase.
