The R1 Concepts 633-32012L RNC Drilled & Slotted Brake Rotor is a high-performance, single left-side disc brake rotor engineered to deliver superior stopping power over stock replacement rotors.

Key Features:

• Cross-Drilled Holes: Reduce heat buildup on the rotor surface, improving fade resistance and extending pad life
• Diamond Slotted Pattern: Continuously sweeps away brake dust, gas, and debris from the pad contact surface, preventing glazing and maintaining consistent bite
• Zinc-Plated Finish: Corrosion-resistant coating protects the rotor hub and vane structure for improved longevity and appearance
• High-Grade Cast Iron Construction: Manufactured with multiple alloys for optimal heat dissipation and structural integrity
• Mill-Balanced Design: Precision-balanced during manufacturing to eliminate vibration and ensure smooth, quiet braking performance
• Direct OEM Replacement Fitment: Engineered to match original equipment mounting dimensions for straightforward installation
• Single Left-Side Rotor: Sold individually; designed for the driver-side position
