R1 Concepts 613-45002R RNC Series Slotted Brake Rotor

The R1 Concepts 613-45002R RNC Series Slotted Brake Rotor is a performance-grade replacement rotor engineered to deliver consistent, fade-resistant stopping power. Designed as a direct OEM-style fitment with performance upgrades, this rotor features precision-cut slots that continuously sweep the brake pad surface to expel heat, gas, and debris — keeping the contact area clean and maximizing braking efficiency.

R1 Concepts manufactures this rotor using high-carbon gray iron for superior thermal conductivity and resistance to warping under repeated heavy braking. Each rotor is computer-balanced and finished with a non-directional surface grind to ensure immediate, even pad break-in from the first stop.

Key Features:

• Slotted Surface Design: Precision-machined slots clear gas, dust, and debris for consistent pad bite and reduced fade
• High-Carbon Gray Iron Construction: Delivers improved heat dissipation and long-term rotor durability
• Direct OEM Replacement Fit: Bolt-on installation with no modifications required
• Computer Balanced: Minimizes vibration and pedal pulsation for a smooth, confident braking feel
• Corrosion-Resistant Finish: Zinc dichromate coating on non-friction surfaces protects against rust during storage and initial use
• Non-Directional Surface Grind: Promotes even and rapid pad seating right out of the box

The R1 Concepts RNC slotted rotor is an ideal upgrade for drivers seeking improved thermal performance and pad response over a standard OEM smooth rotor, while maintaining a streetable, daily-driver-friendly setup.
