R1 Concepts 633-31003L RNC Drilled & Slotted Brake Rotor - Left

The R1 Concepts 633-31003L is a high-performance drilled and slotted brake rotor engineered for drivers who demand superior stopping power and thermal management. Part of R1 Concepts' RNC (R1 Night Camo) series, this left-side rotor features an aggressive combination of cross-drilled holes and milled slots designed to enhance braking performance under both everyday and demanding driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce unsprung weight and allow heat, gas, and debris to escape, while slots continuously clean and refresh the brake pad surface for consistent bite
• High-Carbon Grey Iron Construction: Precision-cast from high-carbon grey iron for improved thermal capacity, reduced noise, and longer rotor life compared to standard rotors
• Zinc Dichromate Coating: Protective anti-rust coating on non-friction surfaces prevents corrosion and maintains a clean, finished appearance
• Precision Balanced: CNC-machined to tight tolerances to eliminate vibration, pedal pulsation, and brake shudder
• Direct-Fit Replacement: OE-style hub and mounting dimensions for a straightforward, no-modification installation
• Left Side (Driver's Side): Designed specifically as a left-side replacement rotor — sold individually

The R1 Concepts 633-31003L is an ideal upgrade for enthusiasts looking to improve braking response and heat dissipation over stock rotors.
