R1 Concepts 633-31146D RNC Drilled & Slotted Brake Rotor

The R1 Concepts 633-31146D RNC Series Drilled and Slotted Brake Rotor is a performance-grade brake rotor engineered for drivers who demand more than standard OEM braking performance. Combining drilled holes and machined slots across the rotor face, this rotor delivers enhanced heat dissipation, improved bite, and consistent pedal feel under a wide range of driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce heat buildup and rotor weight, while machined slots continuously sweep brake pad gases and debris away from the contact surface for maximum stopping power
• RNC Series Construction: R1 Concepts' RNC line is precision-engineered to meet or exceed OEM specifications for a direct, no-modification fit
• Zinc Dichromate Coating: Protective coating on the non-swept surfaces resists corrosion and rust for a clean, long-lasting appearance
• Computer-Balanced: Each rotor is computer tested and balanced to minimize vibration and brake pedal pulsation
• G3000 Castings: Manufactured from high-grade G3000 gray iron for consistent performance, durability, and proper heat management
• Direct OEM Replacement: Engineered as a direct replacement for the factory rotor with no modifications required for installation

The R1 Concepts RNC Series rotor is an ideal upgrade for daily drivers and performance enthusiasts alike, offering improved braking response and fade resistance compared to standard smooth rotors. Sold individually — confirm quantity needed for your application.
