R1 Concepts 623-11005R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-11005R RNC Series Drilled Brake Rotor is a precision-engineered performance disc brake rotor designed to deliver consistent, reliable stopping power. Manufactured from high-grade grey iron, this rotor is cross-drilled to enhance thermal management, reduce brake fade, and improve wet-weather braking performance.

Key Features:

• Cross-Drilled Design: Strategically placed drill holes allow heat, gas, and water to escape from the rotor surface, reducing brake fade and improving pad bite under demanding conditions
• High-Grade Grey Iron Construction: Provides excellent thermal conductivity, durability, and consistent braking performance across a wide range of temperatures
• Precision Machined: Computer-balanced and machined to strict dimensional tolerances for smooth, vibration-free operation and minimal runout
• Direct OE-Style Replacement: Engineered as a direct-fit replacement for OEM rotors — no modifications required for installation
• R1 Concepts RNC Series: Part of R1 Concepts' performance rotor lineup, offering an upgrade over standard OEM rotors for drivers seeking improved braking response

R1 Concepts is a Los Angeles-based manufacturer with over 20 years of brake technology expertise, offering one of the most extensive brake catalogs in the industry. The 623-11005R is manufactured to meet or exceed OEM specifications while delivering the performance advantages of a cross-drilled rotor design.
