R1 Concepts 830-31095L DFC GeoPerformance Drilled and Slotted Brake Rotor - Left

The R1 Concepts 830-31095L DFC GeoPerformance Brake Rotor is a premium drilled and slotted performance rotor engineered for drivers who demand superior stopping power, heat management, and long-lasting durability. Manufactured by Dynamic Friction Company (DFC) — the performance division behind R1 Concepts rotors — this is the driver-side (left) rotor finished with DFC's signature Geomet corrosion-resistant coating.

Key Features:

• Cross-Drilled and Slotted Design: The combination of drilled holes and machined slots improves brake pad bite, reduces stopping distances, and enhances wet-weather braking performance
• Drilled Holes for Heat Dissipation: Strategically placed cross-drill holes allow heat to escape from the rotor surface, reducing brake fade during spirited or demanding driving
• Slots for Gas and Debris Evacuation: Machined slots continuously sweep the brake pad surface, removing gases, dust, and debris for consistent, fade-resistant braking
• Geomet Anti-Corrosion Coating: The full rotor surface — including the hat, vanes, and edges — is treated with a silver Geomet coating to resist rust and corrosion; the braking surface coating naturally wears away during the break-in process
• Direct-Fit Replacement: Designed as a direct OEM replacement requiring no modifications for installation
• Driver-Side Application: This is the left (driver-side) rotor — confirm your vehicle application before ordering

The DFC GeoPerformance series delivers a measurable upgrade over standard OEM rotors, making it an excellent choice for performance-minded drivers seeking improved braking response on the street or track. A proper break-in (bed-in) procedure is recommended after installation to maximize rotor and pad performance.
