R1 Concepts 830-67104L Carbon GEOMET Front Left Drilled & Slotted Brake Rotor

The R1 Concepts 830-67104L is a Carbon GEOMET Series front left drilled and slotted brake rotor engineered for drivers who demand superior stopping power, durability, and corrosion resistance. Featuring a silver zinc GEOMET® finish, this single rotor is built to outperform standard replacement rotors in both everyday driving and more demanding conditions.

Key Features:

• Cross-Drilled & Diamond Slotted Design: Reduces heat buildup on the rotor surface, evacuates brake dust and debris, and helps prevent pad glazing for consistent, reliable braking performance
• Carbon GEOMET® Finish: A proprietary long-lasting corrosion protection coating that keeps the hub and inner vane structure protected throughout the life of the rotor
• High Carbon Casting: Enhanced carbon, molybdenum, and chromium content in the iron casting improves noise dampening characteristics while delivering superior strength, stability, and durability
• Front Left Position: Sold individually as a single rotor for the front left position
• Silver Zinc Coating: Full silver zinc coating on delivery; the braking surface coating wears away during the break-in process, leaving the hub and vane structure coated for corrosion resistance
• Direct Fit: No modifications required for installation

Break-In Note: When first received, the rotor is fully covered in silver zinc coating. During the initial bed-in process, the coating on the braking surface (where the pads contact the rotor) will wear off — this is normal and expected. Only the hub and inner vane structure remain coated after break-in.

The R1 Concepts Carbon GEOMET Series drilled and slotted brake rotor delivers long-lasting performance and protection, making it an excellent upgrade over OEM rotors for performance-oriented street driving.
