R1 Concepts 631-92017R RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92017R RNC Series Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power and heat dissipation over the OEM equivalent. Combining precision drill holes and aggressive machined slots, this rotor is designed for drivers who demand more from their braking system.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor weight and allow heat, gas, and debris to escape, while the slots continuously clean and deglaze brake pad surfaces for consistent bite
• High-Carbon Iron Construction: Premium metallurgy provides strength, durability, and resistance to thermal cracking under heavy braking loads
• Precision Machined: Computer-balanced and precision-turned to strict tolerances for minimal runout and vibration-free performance
• Zinc Dichromate Coating: Corrosion-resistant finish protects non-swept rotor surfaces from rust and enhances appearance
• Direct OEM Replacement: Bolt-on fitment with no modifications required for a straightforward installation
• Improved Thermal Performance: Enhanced ventilation channels promote faster cooling to reduce brake fade during repeated or aggressive stops

The R1 Concepts RNC Series rotor is an ideal upgrade for street performance and spirited driving applications. Pair with R1 Concepts brake pads for a matched system that maximizes braking efficiency and pad life.
