R1 Concepts 613-48012R RNC Series Slotted Brake Rotor

The R1 Concepts 613-48012R is a slotted brake rotor from R1 Concepts' RNC (Race Series) lineup, engineered to deliver improved stopping performance over standard smooth rotors. The precision-machined slots cut across the rotor face serve a dual purpose: continuously sweeping the brake pad surface clean of gas, heat, and debris while maintaining a consistent bite edge for reliable, fade-resistant braking.

R1 Concepts rotors are manufactured using G3000-grade cast iron, meeting or exceeding OEM metallurgical standards for durability and heat dissipation. Each rotor undergoes computer-balanced machining to minimize vibration and pedal pulsation, and is treated with a zinc dichromate coating on non-braking surfaces to resist rust and corrosion during storage and installation.

Key Features:

• Slotted rotor design for improved heat dissipation and pad degassing
• G3000-grade cast iron construction for OEM-equivalent durability
• Computer-balanced for smooth, vibration-free braking
• Zinc dichromate coating on hat and non-friction surfaces for corrosion resistance
• Direct OEM replacement — no modifications required for installation
• Manufactured to strict dimensional tolerances for proper caliper and pad fitment

Ideal for drivers seeking an upgrade from stock rotors with enhanced performance characteristics, the R1 Concepts RNC slotted rotor is a bolt-on solution suitable for daily driving, towing, and performance-oriented street use.
