Dynamic Friction 4002-63174 GeoSpec Coated Drilled and Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4002-63174 GeoSpec Coated Drilled and Slotted Brake Rotor delivers enhanced braking performance and long-lasting corrosion resistance in a direct OE replacement package. Engineered with DFC's proprietary GeoSpec coating, this rotor arrives ready to install with no additional degreasing or preparation required — saving time and labor during the brake job.

The drilled and slotted surface design works together to maximize stopping power and rotor longevity. Cross-drilled holes — which are chamfered to reduce the risk of cracking — dissipate heat that builds up during braking, while the machined slots continuously sweep brake dust, gases, and road debris away from the pad surface to prevent glazing and maintain consistent bite. The result is shorter stopping distances, especially in wet-weather conditions.

Key Features:

• GeoSpec Coating: Proprietary silver-gray finish provides superior corrosion protection compared to conventional zinc or paint coatings — and is safely swept away by friction material during break-in with no harmful effects
• Premium G3000/G11H18 Iron Casting: Engineered for strength, stability, and long-term durability
• Drilled Holes: Chamfered cross-drilled holes reduce rotor heat buildup and minimize cracking risk
• Machined Slots: Remove brake dust, gases, and debris from the pad surface; prevent glazing and improve wet-weather grip
• CNC-Machined Tolerances: Each rotor is precision-machined to the tightest tolerances available
• OE Vane Configuration: Maintains proper and maximum heat dissipation consistent with original equipment design
• 100% Mill-Balanced: Precision cut and electronically mill-balanced for smooth, vibration-free stopping at any speed
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in and quieter, smoother stops
• Ready to Install: Ships dry with no oil coating — no pre-degreasing needed
• Direct OE Replacement: Designed to meet the same form, fit, and function as the original equipment rotor; no modifications required

The DFC 4002-63174 GeoSpec drilled and slotted rotor is an ideal upgrade for drivers seeking improved braking performance and better corrosion resistance over a standard blank replacement rotor. Sold individually.
