Dynamic Friction 830-72070L GeoPerf Drilled & Slotted Disc Brake Rotor

The Dynamic Friction Company 830-72070L GeoPerformance Drilled and Slotted Brake Rotor is a directional, left-side disc brake rotor engineered to deliver enhanced stopping performance over standard OEM rotors. Built with premium G3000/G11H18 cast iron metallurgy, this rotor is designed to match or exceed OE specifications for strength, stability, and durability.

The cross-drilled holes reduce heat buildup on the rotor surface during braking, and are chamfered to minimize the risk of cracking under repeated thermal stress. The machined slots sweep away brake dust, gases, road debris, and water, improving pad bite and maintaining consistent friction — especially in wet conditions.

Key Features:

• Drilled & Slotted surface for improved heat dissipation, pad bite, and wet-weather braking
• Chamfered cross-drill holes to reduce cracking potential
• Directional rotor design — left-side specific (confirm right-side part number separately)
• Premium G3000/G11H18 iron casting for OE-level strength, stability, and reliability
• CNC-machined to tight tolerances for smooth, vibration-free stops
• 100% precision mill-balanced for consistent performance at all speeds
• GeoSpec Silver Grey hat finish for a clean, corrosion-resistant appearance
• Zinc-plated coating on hub, vents, and rotor edge for rust resistance
• Center hole diameter: 68 mm
• Direct bolt-on fitment — no modifications required

The DFC 830-72070L is manufactured to pass a 100% electronic inspection process measuring over 20 quality attributes, ensuring every rotor meets or exceeds OEM standards. It is an ideal upgrade for drivers seeking improved braking confidence for daily commuting or performance street driving.
