R1 Concepts 631-56006D RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-56006D is an RNC series drilled and slotted brake rotor engineered to deliver enhanced stopping performance over standard OEM rotors. Manufactured from high-quality G3000 grade iron, this rotor provides the strength, stability, and durability needed for confident braking in everyday and performance driving conditions.

Key Features:

• Cross-Drilled Holes: Countersunk precision-drilled holes maximize heat dissipation, reduce thermal stress, and help prevent cracking under repeated hard braking
• Diamond Slotted Design: Exclusive slot pattern increases brake pad bite, clears dust and gas buildup, and acts as a wear indicator over the life of the rotor
• G3000 Iron Construction: High-grade iron casting delivers OEM-level strength with improved thermal capacity and long service life
• Direct Fit / No Modification Required: Built to OEM specifications for a straightforward drop-in installation
• Zinc Plated Coating: Protects non-braking surfaces from corrosion, extending rotor life and maintaining appearance

R1 Concepts is a Los Angeles-based manufacturer with over 20 years of brake engineering expertise, offering one of the most extensive brake catalogs in the industry. The 631-56006D is sold as a single rotor — confirm front or rear position and quantity needed for your application.
