R1 Concepts 623-28004R RNC Series Drilled Brake Rotor

The R1 Concepts 623-28004R RNC Series Drilled Brake Rotor is a direct OE-style replacement rotor engineered for consistent stopping performance and long-lasting durability. Designed as a bolt-on replacement, this rotor installs with no modifications required, making it an ideal upgrade or like-for-like swap for worn factory hardware.

R1 Concepts manufactures this rotor from high-quality G3000 grey iron, the same grade of cast iron used by OEM suppliers, ensuring proper heat absorption and dissipation under a wide range of driving conditions. The drilled pattern reduces rotor weight and helps evacuate heat, gas, and water from the rotor face, contributing to more consistent brake feel and reduced fade during repeated stops.

Key Features:

• Drilled hole pattern for improved heat dissipation and reduced brake fade
• G3000 grey iron construction for OE-equivalent strength and longevity
• Direct bolt-on fit — no modifications required
• Zinc dichromate coating on non-friction surfaces to resist corrosion and rust
• Precision-machined to strict OE tolerances for minimal runout and vibration-free braking
• Balanced vane design promotes even airflow for effective thermal management

The R1 Concepts RNC line is built for drivers who want a reliable, no-nonsense brake rotor that meets or exceeds OE performance standards. Whether you're replacing a warped or worn rotor, the 623-28004R delivers confident, consistent braking right out of the box.
