Dynamic Friction 4004-63141 GeoSpec Coated Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4004-63141 GeoSpec Coated Slotted Brake Rotor delivers a performance-oriented braking upgrade with the corrosion resistance of DFC's proprietary GeoSpec coating technology. Engineered to meet or exceed OEM specifications, this slotted rotor is built for drivers who demand reliable stopping power and long-lasting durability.

GeoSpec Coating Technology:

DFC's GeoSpec coating is specially formulated to create a durable, attractive silver-gray finish that provides superior corrosion protection compared to conventional paint or zinc coatings, helping the rotor maintain its appearance and integrity over time.

Slotted Rotor Design:

The precision-machined slots continuously sweep away brake dust, road debris, and gas buildup from the pad surface, preventing pad glazing and maintaining consistent bite for improved stopping performance — especially beneficial in wet or demanding driving conditions.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and durability
• CNC-machined to the tightest tolerances for precise fit and performance
• Original Equipment (OE) vane configuration for proper and maximum heat dissipation
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional finish to promote faster break-in and smoother stops
• Superior corrosion protection over zinc and conventional paint coatings
• Designed to meet OEM form, fit, and function — direct bolt-on replacement

The DFC 4004-63141 is a straightforward, no-modification-required replacement that brings performance slotted rotor benefits together with the proven durability of GeoSpec coating, making it an excellent choice for daily drivers, performance street use, and light towing applications.
