Dynamic Friction 4002-63173 DFC GeoSpec Coated Drilled & Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4002-63173 GeoSpec Drilled and Slotted Brake Rotor delivers an ideal balance of everyday reliability and enhanced stopping performance. Engineered with premium G3000/G11H18 iron castings, this disc brake rotor offers the strength and dimensional stability needed for consistent, confident braking. The proprietary GeoSpec coating forms a durable silver-gray finish that fights rust and corrosion far more effectively than conventional paint or standard zinc coatings.

Key Features:

• GeoSpec Corrosion Protection: Advanced coating provides superior rust resistance over conventional paint or zinc, extending the life of the rotor
• Cross-Drilled Holes: Reduce heat buildup on the rotor surface during repeated braking; chamfered holes minimize the risk of cracking
• Machined Slots: Clear brake dust, pad deposits, and road debris from the rotor surface, preventing pad glazing and improving bite — especially in wet conditions
• Premium G3000/G11H18 Iron Casting: Provides optimal strength, stability, and durability for long service life
• OE Vane Configuration: Maintains original equipment vane geometry to ensure proper heat dissipation
• CNC-Machined to Tight Tolerances: 100% precision cut and mill-balanced for smooth, vibration-free stops at any speed
• Non-Directional Finish: Promotes faster break-in and smoother initial stops right out of the box
• Direct OE Replacement: Bolt-on fitment with no modifications required

The DFC GeoSpec Drilled and Slotted rotor is an excellent upgrade for drivers seeking improved thermal management and consistent performance over a standard blank rotor, without sacrificing the durability and fit expected from a direct OE replacement part.
