R1 Concepts 613-40047R RNC Series Slotted Brake Rotor

The R1 Concepts 613-40047R RNC Series Slotted Brake Rotor is a direct-fit performance replacement rotor engineered for improved braking performance and extended rotor life. Featuring precision-cut slots across the rotor face, this rotor continuously sweeps the brake pad surface to expel heat, gas, and debris — maintaining consistent bite and a clean pad face throughout the life of the rotor.

R1 Concepts manufactures this rotor from high-carbon gray iron for superior heat dissipation and fade resistance. Each rotor is precision-balanced and computer-optimized to ensure smooth, vibration-free stops and a precise fit on your vehicle's hub assembly.

Key Features:

• Slotted Design: Precision-machined slots evacuate heat, gas, and brake dust for consistent, fade-resistant stopping power
• High-Carbon Gray Iron: Improves thermal capacity and reduces the risk of cracking under hard braking
• Computer-Balanced: Minimizes vibration and brake pedal pulsation for a smooth feel
• Direct OE Replacement: Bolt-on fitment with no modifications required
• Corrosion-Resistant Finish: Zinc or e-coating on non-friction surfaces helps prevent rust and corrosion during storage and installation
• RNC Series: R1 Concepts' slotted-only line, ideal for street and light performance driving

The R1 Concepts RNC Series rotor is a strong upgrade from a plain OE-style rotor, offering improved performance characteristics while maintaining full street legality. It is designed for easy installation and is an excellent choice for drivers looking to upgrade their braking system without sacrificing daily drivability.
