R1 Concepts 830-76091L DFC GeoPerformance Drilled Slotted Brake Rotor - Left

The R1 Concepts 830-76091L is a high-performance cross-drilled and diamond slotted brake rotor featuring advanced GEOMET corrosion-resistant coating. The genuine GEOMET finish is applied throughout the entire rotor and promises superior corrosion protection, making this rotor ideal for drivers who demand both performance and durability.

Key Features:

• Cross-drilled and diamond slotted design provides maximum benefits in stopping power, durability, and performance
• Precision-drilled holes with countersunk design reduce heat buildup by up to 105°F and prevent cracking
• Diamond slot technology removes brake and road debris while preventing pad glazing, with diamond tipped ends serving as wear indicators
• GEOMET coating provides excellent cyclic corrosion performance through heat, salt spray, and humidity exposure
• Built to OEM specifications for direct fitment with no modifications required
• Constructed from G3000 grade cast iron for strength, stability, and durability
• GEOMET coating is processed dry, shipped dry, and ready to install without additional preparation

These rotors are designed for high-performance driving and can withstand everyday street driving, track racing, off-roading, and towing/hauling applications. The environmentally friendly GEOMET coating meets EPA regulations and automotive manufacturer standards including Chrysler CS-9003, General Motors GMW 3059, and Ford WSS-M99P9999-A1.

Note: When first received, rotors are completely covered with the coating; during the initial bed-in process, the coating on the braking surface will wear off, leaving only the hub and inner vane structure protected. This rotor is side-specific (Left).
