R1 Concepts 623-31089L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-31089L is a cross-drilled brake rotor from the RNC Series, engineered to deliver improved braking performance over standard OE rotors. Designed as a direct-fit, left-side (driver side) replacement, this rotor installs without modification for a straightforward upgrade.

R1 Concepts RNC Series rotors feature a precision-drilled pattern that helps dissipate heat and gases generated during hard braking, reducing brake fade and improving pedal feel. The rotors are manufactured to OE specifications for a proper fitment and balanced, quiet operation.

Key Features:

• Cross-Drilled Design – Improves heat dissipation and reduces brake fade during repeated or heavy braking
• Direct OE Replacement – Engineered to match original equipment specifications for hassle-free installation
• Left Side (Driver Side) – Sold individually; designed specifically for the left-front or left-rear position
• High-Carbon Gray Iron Construction – Provides strength, durability, and consistent rotor performance
• Corrosion-Resistant Coating – Protective finish on the hat and non-friction surfaces to resist rust
• Precision Balanced – Minimizes vibration and noise for smooth, quiet braking

The R1 Concepts 623-31089L drilled brake rotor is an ideal upgrade for drivers seeking better thermal management and improved braking confidence. Compatible with OE brake pads and calipers, it is a plug-and-play solution for your vehicle's braking system.
