R1 Concepts 623-45016R RNC Series Drilled 1-Piece Brake Rotor

The R1 Concepts 623-45016R RNC Series Drilled Brake Rotor is a performance-engineered disc brake rotor designed as a direct-fit replacement that delivers enhanced stopping power over standard OEM rotors. Precision-drilled holes allow heat, gas, and moisture to escape quickly from the braking surface, reducing brake fade and maintaining consistent pedal feel under demanding driving conditions.

Key Features:

• Precision Cross-Drilled Design: Countersunk drill holes are engineered to maximize heat dissipation and help prevent surface cracking under thermal stress
• Direct-Fit Replacement: Vehicle-specific geometry ensures no modifications are required for installation
• Zinc Plated Finish: Protective zinc coating guards against corrosion on non-braking surfaces, extending rotor service life and maintaining appearance
• Gray Iron Construction: High-quality gray iron casting provides the durability, strength, and noise-dampening characteristics needed for reliable everyday use
• Single Piece (1PC) Design: Rigid one-piece construction delivers consistent, predictable braking response
• Right/Passenger Side: Designed specifically for the passenger (right) side position — sold as a single rotor

R1 Concepts recommends replacing brake pads whenever installing new rotors and following a proper bed-in procedure to fully seat the pads to the rotor surface. For best results, pair with compatible R1 Concepts brake pads or OEM-equivalent ceramic or semi-metallic pads.
