Dynamic Friction 4002-63126 GeoSpec Coated Drilled & Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4002-63126 GeoSpec Coated Drilled and Slotted Brake Rotor delivers enhanced stopping performance and superior corrosion resistance in a direct OE-replacement design. Finished in DFC's proprietary GeoSpec silver-gray coating, this rotor arrives ready to install with no degreasing or additional prep required.

GeoSpec Coating Technology:

DFC's GeoSpec coating forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings. The coating is safely swept away by the brake pad friction material during break-in, leaving no harmful residue and saving significant time during installation.

Drilled & Slotted Performance Design:

• Cross-drilled holes reduce heat buildup on the rotor surface and are chamfered to minimize cracking risk
• Machined slots continuously sweep brake dust, road debris, and gases away from the pad surface, preventing pad glazing
• Combined drill-and-slot pattern increases brake pad bite for shorter stopping distances, especially in wet weather conditions

Key Features:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and durability
• CNC-machined to the tightest tolerances available
• OE vane configuration for proper and maximum heat dissipation
• 100% precision cut and mill-balanced for smooth stops and zero vibration at any speed
• Non-directional surface finish promotes faster break-in and smoother, quieter stops
• All vented rotors are 100% inspected for balance and corrected with an electronic mill-balance process
• Designed to meet the same form, fit, and function as OEM brake rotors — no modifications required

The DFC 4002-63126 is sold individually and is an ideal upgrade for drivers seeking improved braking performance and long-lasting corrosion protection over a standard OE replacement rotor.
