R1 Concepts 623-13036R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-13036R is a RNC Series cross-drilled brake rotor engineered to deliver improved stopping performance over standard OEM replacement rotors. Manufactured to original equipment specifications, this rotor installs as a direct-fit replacement with no modifications required.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to reduce heat buildup, improve ventilation, and minimize the risk of cracking under thermal stress
• G3000 Grade Cast Iron Construction: Manufactured from high-grade G3000 cast iron for excellent strength, stability, and consistent braking power
• Zinc Plated Corrosion Protection: Protective zinc coating applied to the hub, hat, and vane areas guards against rust and extends rotor service life
• Double Disc Ground Surface: The braking surface is double disc ground for a smooth, even finish that promotes faster, more uniform brake pad bed-in and quieter operation
• Direct OEM Fit: Engineered to match original equipment dimensions and bolt patterns — no drilling, cutting, or adapter hardware needed
• Single Rotor (Right Side): Sold individually; the "-R" suffix designates the right/passenger-side rotor position

R1 Concepts brake rotors are designed for everyday street driving, light performance use, and general replacement applications. As with any rotor installation, brake pads should be replaced at the same time and a proper bed-in procedure should be followed to ensure optimal performance and longevity.
