R1 Concepts 631-58007R RNC Series Drilled and Slotted Brake Rotor

The R1 Concepts 631-58007R RNC Series Drilled and Slotted Brake Rotor is a performance-grade replacement disc rotor engineered to deliver superior stopping power over standard OEM rotors. Manufactured from G3000 grade cast iron and built to OEM specifications, this rotor installs without modification and is a direct bolt-on replacement.

Key Features:

• Cross-Drilled Holes: Precision-drilled and countersunk to prevent cracking, improve ventilation, and dissipate heat — reducing rotor surface temperatures for consistent braking performance
• Diamond Slot Technology: Slots remove brake dust and road debris from the pad contact surface, prevent pad glazing, extend pad and rotor life, and serve as a wear indicator — when the slot tips are gone, it's time for replacement
• Zinc Plated Coating: Full silver zinc plating protects the rotor from corrosion, improving appearance and longevity; the coating naturally wears away from the braking surface during the break-in process while protecting the hub and inner vane structure throughout the life of the rotor
• G3000 Cast Iron Construction: High-grade iron casting meets or exceeds OEM material standards for durability and thermal stability
• Direct OEM Replacement: Designed to OEM specifications for a no-modification, bolt-on installation

R1 Concepts RNC Series rotors are well-suited for daily drivers, street performance builds, light towing and hauling, and mild off-road use. A proper break-in procedure is recommended after installation to ensure optimal pad transfer and braking performance.
