R1 Concepts 613-39017R RNC Series Slotted Brake Rotor

The R1 Concepts 613-39017R RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers seeking improved braking response and consistent stopping power. R1 Concepts manufactures their rotors to meet or exceed OEM specifications, making this a direct-fit replacement that requires no modification for installation.

The slotted rotor design features precision-machined slots across the rotor face, which continuously clean and degas the brake pad surface during braking. This helps prevent brake fade, reduces heat buildup, and maintains reliable pad-to-rotor contact under demanding driving conditions.

Key Features:

• Slotted Design: Precision slots sweep away gas, dust, and debris from the pad surface for consistent bite and reduced fade
• OEM-Grade Fitment: Machined to original manufacturer specifications for a direct, no-modification installation
• Thermal Management: Vented construction promotes airflow and heat dissipation to extend rotor and pad life
• Corrosion-Resistant Finish: Protective coating on non-contact surfaces resists rust and improves appearance
• Balanced Construction: Each rotor is precision balanced to minimize vibration and pedal pulsation
• Street and Performance Use: Suitable for daily driving and spirited performance applications

R1 Concepts rotors undergo rigorous quality control and are manufactured from high-carbon gray iron, providing excellent durability and thermal stability. The RNC (Rotor No Coating) designation indicates a non-coated rotor optimized for consistent pad bite and performance-focused applications.
