R1 Concepts 631-92084R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92084R RNC Series Brake Rotor is a premium drilled and slotted performance rotor designed to deliver improved braking performance over factory-style solid rotors. Engineered for drivers who demand greater stopping power and thermal management, this rotor combines precision cross-drilled holes with machined slots to optimize heat dissipation and outgas brake pad gases during heavy use.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and help dissipate heat, while slots continuously clean and deglaze the brake pad surface for consistent bite
• Premium G3000 Cast Iron: Manufactured from high-grade G3000 metallurgy for durability, quiet operation, and OEM-compatible performance
• Corrosion-Resistant Coating: Non-braking surfaces feature a zinc dichromate or e-coating finish to resist rust and maintain a clean appearance
• Precision Balanced: Each rotor is computer balanced and tested to minimize vibration, pulsation, and pedal feedback
• Direct OE Replacement: Engineered to match OEM specifications for a straightforward, no-modification installation
• Manufacturer Part Number: 631-92084R (Right/Passenger Side)

The R1 Concepts RNC Series rotor is an excellent upgrade for performance-minded drivers looking to improve braking response and thermal capacity while maintaining street-legal reliability. Sold individually — this listing is for the right-side rotor.
