R1 Concepts 623-54046L RNC Series Cross-Drilled Disc Brake Rotor - Left

The R1 Concepts 623-54046L is a cross-drilled disc brake rotor from R1 Concepts' RNC Series, designed as a direct-fit replacement and performance upgrade for the left (driver) side of the vehicle. Engineered to OEM dimensions for a hassle-free installation, this rotor delivers improved braking confidence over stock components.

Key Features:

• Cross-Drilled Design: Strategically placed drilled holes dissipate heat, gas, and water from the braking surface for more consistent, fade-resistant stopping power
• Silver Zinc Plating: Protective zinc coating on the non-braking surfaces guards against corrosion, extending rotor life and maintaining a clean appearance
• Precision Balanced: CNC-machined to tight tolerances for minimal runout and smooth, vibration-free braking
• Direct OEM Replacement: Manufactured to match original equipment dimensions for a bolt-on fit with no modifications required
• High-Carbon Iron Construction: Premium casting material provides superior strength, durability, and thermal capacity compared to standard rotors
• Left-Side Specific: Part number 623-54046L is application-specific to the left (driver) side position

R1 Concepts' RNC Series rotors are an excellent choice for drivers looking to upgrade from worn OEM rotors while gaining the thermal and bite benefits of a drilled rotor design. Sold individually as a single left-side rotor.
