Dynamic Friction 830-54097L DFC GeoPerformance Drilled & Slotted Disc Brake Rotor - Left

The Dynamic Friction Company (DFC) GeoPerformance 830-54097L is a premium drilled and slotted disc brake rotor engineered to deliver enhanced stopping performance over standard OEM rotors. Designed as a direct-fit replacement, this rotor is built to match OE specifications while offering the added benefits of a performance-oriented surface pattern.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce heat buildup on the rotor surface, while slots sweep away brake dust, road debris, and gases to prevent pad glazing
• Chamfered Drill Holes: All cross-drilled holes are chamfered to minimize stress concentration and reduce the potential for cracking under high-heat conditions
• OE Vane Configuration: Each rotor is engineered to match the factory vane layout, including OE split-core technology, to ensure proper and maximum heat dissipation
• Internally Coated Vanes: Cores are treated with a specially formulated paint for a smoother vane finish, improving airflow and reducing the machining needed for proper mill-balancing
• Improved Wet-Weather Performance: The slotted surface pattern bites more aggressively into brake pads, providing shorter stopping distances especially in wet conditions
• Direct OE Replacement: Engineered to meet or exceed original equipment specifications — no modifications required for installation
• Left-Side Fitment: This is the driver-side (left) rotor; sold individually

The DFC GeoPerformance series is the ideal upgrade for drivers seeking more responsive braking without sacrificing daily drivability. Built by Dynamic Friction Company, a leading manufacturer of OE-quality brake components for domestic and foreign vehicles.
