R1 Concepts 613-40001R RNC Series Slotted Brake Rotor

The R1 Concepts 613-40001R RNC Series Slotted Brake Rotor is a performance-grade disc brake rotor engineered to deliver confident, consistent stopping power for daily drivers and performance enthusiasts alike. Featuring R1 Concepts' Diamond Slot Technology, the precision-machined slots channel away heat, brake dust, gases, and road debris from the pad surface, preventing pad glazing and extending the service life of both the pad and the rotor.

Key Features:

• Diamond Slotted Design — Removes brake debris and gases from the contact surface, increasing pad bite and improving overall braking response
• Built-In Wear Indicator — Diamond-tipped slot ends serve as a visual rotor replacement indicator; when the tips wear away, it's time for replacement
• Silver Zinc Plated Coating — Corrosion-resistant finish protects the hub, vanes, and non-braking surfaces for a cleaner appearance and longer rotor life
• G3000 Cast Iron Construction — Meets or exceeds OEM metallurgical specifications for strength, stability, and thermal performance
• OEM-Style Direct Fit — Machined to precise OEM tolerances for a straightforward, no-modification installation
• Suitable for daily driving, street performance, light towing, and hauling applications

The RNC Series represents R1 Concepts' slotted rotor lineup — delivering a meaningful performance upgrade over standard blank OEM rotors without the added complexity of cross-drilling. The zinc coating is applied to the full rotor at the factory; during the break-in process, it naturally wears from the braking surface while remaining intact on the hat and vane structure for lasting corrosion protection.
