R1 Concepts 631-92065R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92065R RNC Series Brake Rotor is a premium cross-drilled and slotted disc brake rotor engineered for drivers who demand reliable, high-performance stopping power. Constructed from high-grade G3000 cast iron, this rotor delivers consistent braking performance under a wide range of driving conditions — from daily commuting to spirited street driving.

Key Features:

• Cross-Drilled & Slotted Design: Drilled holes and machined slots work together to dissipate heat, expel gas buildup, and maintain consistent pad-to-rotor contact for improved brake response
• Zinc Coating: Protective zinc plating on non-braking surfaces guards against rust and corrosion, extending rotor life and maintaining a clean appearance
• G3000 Cast Iron Construction: High-quality iron alloy provides excellent thermal capacity and long-lasting durability
• Precision Machined: CNC-machined to strict tolerances for smooth, vibration-free braking and minimal runout
• Direct OE Replacement Fit: Engineered as a direct replacement for the original equipment rotor — no modifications required for installation
• Balanced Vane Design: Optimized internal vane structure promotes even airflow and efficient heat dissipation during repeated braking

The R1 Concepts RNC Series rotor is sold individually and is ideal for drivers looking to upgrade from a standard OE rotor to a performance-enhanced drilled and slotted unit. A proper break-in (bedding) procedure is recommended after installation to achieve optimal braking performance and pad transfer film.
