Dynamic Friction 830-73017L GeoPerf Drilled & Slotted Disc Brake Rotor - Left

The Dynamic Friction Company (DFC) 830-73017L GeoPerformance Drilled and Slotted Brake Rotor delivers upgraded stopping power and thermal performance over standard blank rotors. Engineered from premium G3000/G11H18 cast iron, this rotor is formulated to match OEM specifications for durability, reliability, and long-term stability.

Key Features:

• Cross-Drilled Holes — Reduces heat buildup on the rotor surface during heavy or repeated braking; chamfered edges minimize the risk of cracking under stress
• Precision Slots — Clear brake dust, road debris, and gases from the pad surface to prevent glazing and maintain consistent bite, especially in wet conditions
• Non-Directional Surface Finish — Promotes faster, more even brake pad bed-in for quieter and smoother stops right out of the box
• Mill-Balanced Construction — 100% electronically inspected and mill-balanced for vibration-free performance at any speed
• Zinc-Plated Silver Finish — Applied to the hub, vents, and rotor edge for enhanced rust and corrosion protection
• G3000/G11H18 Iron Casting — Premium casting specification engineered for OE-level strength, stability, and thermal management
• CNC-Machined to Tight Tolerances — Ensures precise fit and consistent performance with no modifications required
• Direct OE Replacement — Designed to match the original equipment vane configuration for proper and maximum heat dissipation

The 830-73017L is the left (driver) side rotor in the DFC GeoPerformance lineup — ideal for drivers seeking improved braking response in demanding conditions such as frequent stop-and-go traffic, towing, steep grades, or spirited driving. This rotor ships new in box and is ready to install.
