R1 Concepts 613-46000L RNC Series Slotted Brake Rotor

The R1 Concepts 613-46000L is a slotted brake rotor from R1 Concepts' RNC (Race & Performance) line, engineered to deliver consistent stopping power and improved thermal management over OEM rotors. The precision-machined slots help evacuate heat, gas, and debris from the rotor face, maintaining a clean pad contact surface and reducing brake fade under demanding driving conditions.

Key Features:

• Slotted Design: Precision-cut slots sweep away gas, dust, and debris for consistent pad bite and improved braking performance
• Improved Heat Dissipation: Slot geometry promotes airflow and thermal venting to reduce brake fade during repeated or heavy braking
• Direct OEM Replacement: Engineered to match factory mounting specifications for a straightforward, no-modification installation
• High-Carbon Iron Construction: Premium metallurgy provides excellent wear resistance, rotor integrity, and noise reduction
• Zinc-Washed Finish: Corrosion-resistant coating protects non-contact surfaces from rust and environmental exposure
• Left-Side Application: Designed specifically for the driver-side (left) fitment as indicated by the "L" suffix in the part number

R1 Concepts rotors are manufactured to strict dimensional tolerances and undergo stringent quality control to ensure OE-level fit and reliability. The 613-46000L is an ideal upgrade for drivers seeking improved braking response and durability compared to standard replacement rotors.
