Dynamic Friction 810-74030L GeoPerf GeoSpec Coated Slotted Brake Rotor Left

The Dynamic Friction 810-74030L is a GeoPerformance slotted brake rotor from Dynamic Friction Company (DFC), engineered for drivers who demand consistent stopping power and long-lasting durability. Part of DFC's 810 Series, this rotor features a GeoSpec corrosion-resistant coating — a patented paint formulation that forms a durable silver-gray finish proven to outperform conventional paint and zinc coatings, withstanding up to 400 hours of salt spray testing.

Key Features:

• Slotted surface pattern removes brake dust, debris, and gases from the rotor face, prevents pad glazing, and improves pad bite for shorter stopping distances — especially in wet conditions
• Premium G3000/G11H18 cast iron metallurgy engineered for strength, stability, and durability that meets or exceeds OEM specifications
• OE vane configuration ensures proper and maximum heat dissipation through the vented rotor design
• CNC-machined to tight tolerances — Disc Thickness Variation (DTV) max .010 mm, Lateral Runout max .050 mm
• 100% precision mill-balanced for vibration-free, smooth stops at any speed
• Fine-turned finish (1.6 RMS) promotes faster, more even brake pad bed-in
• GeoSpec silver-gray coating on disc, hat, hub, vents, and edges for superior rust protection
• Ready to install — no additional preparation required

Each DFC rotor passes a 100% electronic inspection station measuring over 20 critical attributes before leaving the factory. The 810-74030L is the left/driver-side rotor and is sold individually.
