R1 Concepts 633-31165D RNC Drilled & Slotted Brake Rotor

The R1 Concepts 633-31165D RNC Series Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power and heat dissipation over stock brake components. Combining a precision-drilled and slotted surface pattern, this rotor is designed for drivers who demand more from their braking system—whether on the street or during spirited driving.

Key Features:

• Drilled & Slotted Surface: Cross-drilled holes reduce rotor weight and aid in heat venting, while the machined slots continuously sweep away brake dust, gas, and debris for a cleaner, more consistent bite
• High-Carbon Grey Iron Construction: Precision-poured grey iron compound provides excellent durability, reduced brake fade, and quieter operation compared to standard rotors
• Zinc Dichromate Coating: Protective anti-rust coating on non-friction surfaces prevents corrosion during break-in and storage, maintaining a clean appearance over time
• Direct-Fit OE Replacement: Engineered to exact OEM dimensions for a hassle-free, hardware-store-free installation—no cutting or modifications required
• Balanced & Precision-Machined: Each rotor is computer-balanced and machined to tight tolerances to minimize vibration and pedal pulsation
• RNC Series: Part of R1 Concepts' performance-grade lineup, delivering an upgrade in braking performance over factory rotors at an accessible price point

The R1 Concepts 633-31165D is sold individually. For best results, rotors should be replaced in axle pairs and paired with fresh brake pads. A proper bed-in procedure is recommended after installation to ensure optimal pad-to-rotor contact and maximum braking performance.
