R1 Concepts 623-63088R RNC Series Drilled Brake Rotor

The R1 Concepts 623-63088R RNC Series Drilled Brake Rotor is a premium replacement rotor engineered to deliver consistent, fade-resistant stopping power. Manufactured from high-carbon grey iron, this rotor provides superior heat dissipation and noise dampening compared to standard cast iron rotors, making it an excellent upgrade for daily drivers and performance enthusiasts alike.

The precision-drilled holes across the rotor face serve a dual purpose: they allow heat, gas, and debris to escape the braking surface during hard stops, and they reduce overall rotor weight for improved unsprung mass performance. Each rotor is geometrically matched to OEM specifications for a direct bolt-on fit with no modifications required.

Key Features:

• Drilled rotor design for enhanced cooling and gas venting
• High-carbon grey iron construction for reduced noise and vibration
• Precision-machined to OEM dimensions for direct replacement fit
• Zinc dichromate coating on non-swept surfaces to resist corrosion
• Balanced and tested for smooth, vibration-free braking
• Meets or exceeds OEM performance standards

R1 Concepts rotors are manufactured under strict quality controls to ensure consistent thickness variation (DTV) and lateral runout (LRO) tolerances, helping to eliminate brake pulsation and pedal vibration. The 623-63088R is the right-side (passenger side) rotor and is sold individually.
