R1 Concepts 623-59005R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-59005R is a precision-engineered drilled disc brake rotor from R1 Concepts' RNC Series, designed as a direct-fit replacement that delivers improved braking performance over standard OEM rotors. Manufactured to OEM specifications, this rotor installs without modification for a straightforward, hassle-free swap.

Key Features:

• Cross-Drilled Design: Precision-drilled holes reduce rotor surface heat buildup, improve wet-weather bite, and help outgas brake pad gases for more consistent stopping power
• Chamfered & Countersunk Holes: Holes are chamfered and countersunk to help prevent cracking and maintain rotor structural integrity over time
• G3000 Grade Cast Iron Construction: High-quality gray iron provides excellent thermal stability, noise-dampening properties, and long service life
• Zinc Coating Finish: Protective zinc coating on non-braking surfaces guards against rust and corrosion, keeping the rotor looking clean behind the wheel
• Direct-Fit Replacement: Engineered to OEM dimensions for bolt-on installation with no drilling, cutting, or modifications required
• Vented Design: Internal vane venting promotes airflow through the rotor to dissipate heat and reduce brake fade during repeated stops

The R1 Concepts RNC Series drilled rotor is an ideal upgrade for drivers seeking better heat management and improved wet-weather braking performance compared to a standard blank replacement rotor. Compatible with OEM-style brake calipers and pads.
