R1 Concepts 631-19002R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-19002R RNC Series Brake Rotor is a direct-fit, performance-engineered drilled and slotted disc brake rotor designed to deliver superior stopping power and thermal management over standard OEM rotors. Built to R1 Concepts' exacting quality standards, this rotor is an ideal upgrade for drivers seeking improved brake performance without sacrificing everyday drivability.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce heat buildup and allow gases and debris to escape from the rotor surface, while slots continuously clean and deglaze brake pad surfaces for consistent bite and pedal feel
• G3000 Castings: Manufactured from premium G3000 grey iron casting for outstanding durability, heat resistance, and long service life
• Zinc Dichromate Coating: Non-contact surfaces are coated with a zinc dichromate finish to prevent rust and corrosion, keeping the rotor looking clean and performing reliably
• Direct OE Replacement: Engineered as a direct bolt-on replacement — no modifications required for a straightforward installation
• Precision Balanced: Each rotor is precision-machined to strict tolerances to minimize vibration, runout, and pedal pulsation
• Vented Construction: Internal vane design promotes airflow through the rotor for continuous cooling during aggressive or repeated braking

The R1 Concepts RNC Series is ideal for performance-minded drivers and enthusiasts who want a meaningful upgrade over stock brake components. The combination of drilling and slotting makes this rotor well-suited for spirited street driving, towing, and light track use.
