R1 Concepts 631-31101D RNC Drilled Slotted Disc Brake Rotor

The R1 Concepts 631-31101D is an RNC series drilled and slotted performance disc brake rotor engineered to deliver improved stopping power and thermal management over stock rotors. Cross-drilled holes and precision-cut slots work together to dissipate heat, release gas and debris from the rotor surface, and reduce brake fade during demanding driving conditions.

Key Features:

• Cross-Drilled & Slotted Design: Enhances cooling efficiency and helps expel heat, gases, and dust for more consistent brake performance
• Zinc Plated Coating: Protects against corrosion for improved appearance and longer service life
• High-Quality Metallurgy: Manufactured to meet or exceed OE specifications for reliable, fade-resistant braking
• Direct OE Replacement Fit: Designed as a bolt-on replacement requiring no modifications for a straightforward installation
• Vented Construction: Internal vane structure promotes airflow to further reduce operating temperatures

R1 Concepts is a Los Angeles-based manufacturer with over 20 years of brake engineering experience, producing one of the most comprehensive brake catalogs in the industry for both foreign and domestic vehicle applications. The 631-31101D rotor is sold as a single unit and is designed to restore or upgrade braking performance with a precise, vehicle-specific fitment.
