R1 Concepts 623-63034L RNC Series Drilled Brake Rotor

The R1 Concepts 623-63034L RNC Series Drilled Brake Rotor is a high-performance replacement disc brake rotor engineered for improved stopping power and heat dissipation. Featuring a precision-drilled rotor face, this rotor helps evacuate heat, gas, and water from the braking surface for consistent, fade-resistant performance under demanding driving conditions.

Key Features:

• Drilled Design: Cross-drilled holes reduce rotor surface temperature and help clear debris, water, and brake dust for cleaner, more responsive braking
• Precision Machined: CNC-machined to tight tolerances for smooth, vibration-free performance and proper fitment
• Corrosion-Resistant Finish: Zinc dichromate coating protects non-swept areas from rust and corrosion for a clean, long-lasting appearance
• Direct Fit Replacement: Engineered as a direct OE-style replacement for straightforward installation without modifications
• High-Carbon Iron Construction: Cast from high-carbon grey iron for superior heat absorption and durability
• Left Side (Driver Side): This is the left/driver-side rotor (designated by the "L" suffix in the part number)

R1 Concepts brake rotors are manufactured to meet or exceed OEM specifications, making the 623-63034L a reliable upgrade for drivers seeking improved braking performance and longevity over standard replacement rotors.
