R1 Concepts 613-03063L RNC Series Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-03063L RNC Series Slotted Brake Rotor is a performance-engineered replacement rotor designed to deliver consistent, fade-resistant stopping power. The "L" suffix designates the left (driver) side fitment, so always confirm pairing with the correct right-side counterpart for a full axle replacement.

Key Features:

• Slotted Rotor Design: Precision-cut slots channel heat, gas, and debris away from the rotor face, maintaining consistent pad-to-rotor contact and reducing brake fade under demanding conditions
• High-Carbon Gray Iron Construction: Provides excellent thermal conductivity and durability, reducing warping and cracking over the rotor's service life
• Directional Venting: Internal vane design promotes airflow through the rotor for rapid heat dissipation
• Corrosion-Resistant Coating: Non-braking surfaces feature a zinc dichromate finish to resist rust and maintain a clean appearance
• Direct OE Replacement: Manufactured to meet or exceed original equipment specifications for a straightforward, no-modification installation
• Left/Driver Side Specific: MPN suffix "L" confirms this is the driver-side rotor; must be installed on the correct side

R1 Concepts rotors are precision balanced and finished to strict tolerances, ensuring minimal runout and vibration-free braking. The RNC slotted line is an ideal upgrade for drivers seeking improved braking performance over standard OE smooth rotors without the aggressive wear profile of drilled designs.
