R1 Concepts 631-92031R RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92031R RNC Series Drilled & Slotted Brake Rotor delivers enhanced braking performance over standard OEM rotors. Engineered to meet or exceed OEM specifications, this rotor is a direct bolt-on replacement requiring no vehicle modification.

The combined drilled and slotted surface design serves a dual purpose: precision-drilled holes improve heat dissipation and ventilation, while machined slots continuously sweep the brake pad surface clean of gas, dust, and debris — reducing pad glazing and maintaining consistent bite throughout the rotor's service life.

Key Features:

• Drilled and slotted rotor design for improved cooling and pad degassing
• Cast from G3000 grade cast iron for durability and consistent performance
• Silver zinc coating on hat and vane areas provides corrosion resistance
• OEM-spec geometry ensures direct, no-modification fitment
• Balanced and precision-machined to minimize vibration and brake pedal pulsation
• Suitable for street and light performance driving applications

The R1 Concepts RNC Series rotor is an ideal upgrade for drivers seeking improved braking feel and rotor longevity without the cost of a full big-brake kit. Each rotor is sold individually.
