Dynamic Friction 4002-63113 GeoSpec Coated Drilled & Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4002-63113 is a GeoSpec Coated Drilled and Slotted Disc Brake Rotor engineered to deliver enhanced stopping performance and superior corrosion resistance over standard OEM-style rotors. Featuring a distinctive silver-gray GeoSpec coating, this rotor resists rust and corrosion far better than conventional paint or zinc coatings, and arrives ready to install straight out of the box—no cleaning or prep required.

Drilled & Slotted Performance Benefits:

• Cross-drilled holes reduce heat buildup on the rotor surface during heavy braking; holes are chamfered to minimize cracking risk
• Machined slots sweep away brake dust, road debris, and gases, preventing pad glazing and improving bite—especially in wet conditions
• Non-directional rotor finish promotes faster, more even brake pad bed-in for quieter and smoother stops
• GeoSpec patented coating forms a durable silver-gray finish that fights rust far better than conventional paint or zinc coatings
• Ships dry and fully prepped—no oil coating to clean off before installation

Precision Engineering:

• Cast from premium G3000/G11H18 iron for strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available
• Original Equipment (OE) vane configuration for proper and maximum heat dissipation
• 100% precision cut and mill-balanced for vibration-free stopping at any speed
• Designed to meet OEM form, fit, and function as a direct replacement rotor

The DFC 4002-63113 GeoSpec Drilled and Slotted rotor is an ideal upgrade for drivers seeking improved braking performance, better heat management, and long-lasting corrosion protection in a direct-fit OE replacement package.
