R1 Concepts 631-92075L RNC Drilled & Slotted Brake Rotor - Left

The R1 Concepts 631-92075L RNC Drilled & Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand superior stopping power and thermal management. This left-side rotor features a combination of cross-drilled holes and milled slots to maximize braking performance under both everyday and demanding driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and allow heat, gas, and debris to escape, while the slots continuously clean and refresh the brake pad surface for consistent bite
• Enhanced Thermal Dissipation: The vented construction promotes airflow to keep rotor temperatures in check, reducing brake fade during repeated or heavy stops
• High-Carbon Gray Iron Construction: Provides excellent durability, reduced noise, and improved wear resistance compared to standard rotors
• Zinc Dichromate Coating: Non-friction surfaces are coated to resist corrosion and maintain a clean appearance throughout the rotor's service life
• Direct OE Replacement: Engineered to match original equipment specifications for a straightforward, no-modification installation
• Left-Side Fitment: This unit (suffix "L") is designated for the left (driver's side) wheel position

R1 Concepts brake rotors are precision-balanced and manufactured to strict dimensional tolerances, ensuring smooth, vibration-free braking performance. The 631-92075L is an ideal upgrade for drivers looking to improve braking response and longevity over standard OEM rotors.
