R1 Concepts 623-47065L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-47065L RNC Series Drilled Brake Rotor is a direct-fit, performance-oriented disc brake rotor engineered to deliver reliable stopping power and improved thermal management over stock rotors. This is a single left (driver-side) rotor designed as a direct OEM replacement with a performance upgrade.

Key Features:

• Cross-Drilled Design: Drilled holes help dissipate heat and gas buildup during braking, reducing brake fade and improving overall rotor longevity
• Silver Zinc Plated Coating: Corrosion-resistant finish protects the rotor hub and vane structure from rust and oxidation, extending service life and maintaining a clean appearance
• Direct-Fit Replacement: Engineered to OEM specifications for a hassle-free, bolt-on installation with no modifications required
• Left (Driver) Side: This is a single rotor for the left/driver side — part suffix "-L" designates driver-side fitment
• Premium G3000 Metallurgy: Cast from high-grade G3000 grey iron for consistent friction performance, structural integrity, and even heat distribution
• Vented Construction: Internal vane structure promotes airflow through the rotor for continuous cooling during repeated brake applications

R1 Concepts manufactures performance brake components that meet or exceed OEM standards. The RNC Series rotor is compatible with a wide range of OEM-style brake pads and is suitable for everyday street driving. A proper bed-in procedure is recommended after installation to seat the rotor surface and maximize braking performance.
