Dynamic Friction 4004-63071 GeoSpec Coated Drilled & Slotted Disc Brake Rotor Set

The Dynamic Friction Company 4004-63071 GeoSpec Coated Drilled & Slotted Brake Rotor Set delivers an ideal balance of enhanced braking performance and long-lasting corrosion resistance. This 4-wheel set pairs the trusted DFC GeoSpec protective coating with an aggressive drilled and slotted surface design, making it a direct-fit upgrade over worn OEM rotors.

DFC's proprietary GeoSpec® coating forms a durable, attractive silver-gray finish engineered to fight rust and corrosion far more effectively than conventional paint or zinc coatings. Each rotor arrives processed dry and ready to install — no pre-cleaning required.

Drilled & Slotted Performance Benefits:

• Cross-drilled holes reduce heat buildup during hard braking; holes are chamfered to minimize cracking risk
• Machined slots continuously sweep away brake dust, debris, and gases, preventing pad glazing for consistent bite
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter, smoother stops
• Engineered with premium G3000/G11H18 iron castings for strength, stability, and durability
• OE vane configuration maintained for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available
• 100% precision cut and mill-balanced to eliminate vibration at any speed
• All vented rotors are 100% electronically inspected for balance and corrected if necessary

Designed to meet the same form, fit, and function as OEM brake rotors, the 4004-63071 set is an excellent choice for drivers seeking improved stopping performance during normal commutes, performance street driving, towing, or light off-road use.
