R1 Concepts 623-54189R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-54189R RNC Series Drilled Brake Rotor is a direct-fit performance replacement rotor engineered to deliver confident stopping power with improved heat dissipation and a clean, aggressive appearance. Precision-drilled holes across the rotor face allow gases, heat, and debris to escape quickly, reducing brake fade during demanding driving conditions.

Key Features:

• Drilled Rotor Design: Cross-drilled holes promote rapid heat dissipation and help evacuate gas and water from the braking surface for consistent, fade-resistant performance
• OE-Style Direct Fit: Engineered to match original equipment specifications for straightforward, hardware-compatible installation
• Premium Gray Iron Construction: Cast from high-quality gray iron for long-lasting durability and reliable braking performance
• Zinc Plating: Non-braking surfaces feature a zinc-coated finish to resist rust and corrosion, keeping the rotor looking clean behind the wheel
• Precision Balanced: Computer-balanced to minimize vibration and reduce brake pedal pulsation
• Right/Passenger Side: This listing is for the right (passenger) side rotor as denoted by the "R" suffix in the part number

The R1 Concepts RNC Series is an excellent choice for drivers seeking a step up from a standard OEM replacement without sacrificing daily drivability. Designed and tested to meet strict quality standards, this rotor pairs well with R1 Concepts brake pads for a complete, optimized brake system upgrade.
