R1 Concepts 631-92006L RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92006L is a single left-side replacement disc brake rotor from R1 Concepts' RNC (Race-N-Cruise) Series, featuring a cross-drilled and slotted surface pattern engineered to deliver improved braking performance over standard OEM rotors.

Key Features:

• Cross-Drilled Holes: Reduce heat buildup at the rotor surface and help evacuate water and gas for consistent, fade-resistant braking
• Diamond Slotted Pattern: Continuously sweeps brake dust, debris, and gases away from the pad contact surface, preventing pad glazing and maintaining bite throughout the pad's life
• Zinc Dichromate Finish: Protective coating applied to non-contact surfaces resists corrosion and rust, maintaining a clean appearance behind the wheel
• G3000-Grade Cast Iron Construction: Premium iron alloy provides precise thermal management and consistent performance under repeated braking cycles
• Chamfered Drill Holes: Edges of each drilled hole are chamfered to reduce stress concentrations and minimize the risk of cracking
• Left-Side (Driver-Side) Application: Sold as a single rotor; the "L" suffix designates this as the left/driver-side unit
• Direct OEM Replacement Fit: Designed to install using existing hardware with no modifications required

The R1 Concepts RNC Series is suited for drivers seeking an upgrade from stock rotors for spirited street driving, towing, or light performance use. The combination of drilled holes and slots provides enhanced thermal cooling and a consistently clean pad surface, making this rotor a strong performer in both daily-drive and demanding conditions.
