R1 Concepts 623-47042L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47042L RNC Series Drilled Brake Rotor is a performance-grade replacement disc rotor engineered to deliver confident, consistent stopping power. Designed as a direct OEM replacement, this rotor installs without modification and is built to meet or exceed original equipment specifications.

Precision cross-drilled holes throughout the rotor face promote rapid heat dissipation, reduce brake fade, and help evacuate water, gas, and debris from the braking surface — keeping your pads and rotor performing at their best in a wide range of driving conditions. The rotor is coated with a zinc plating finish to guard against corrosion and surface rust, extending service life and maintaining a clean appearance behind the wheel.

Manufactured from G3000 grade cast iron, this rotor provides the strength, thermal stability, and wear resistance expected from a quality performance brake component. The rotor features a double disc grind on the braking surface for a faster, more even brake pad bed-in and quieter operation from the start.

Key Features:

• Cross-drilled design for improved heat dissipation and fade resistance
• Zinc-plated coating for corrosion and rust protection
• G3000 grade cast iron construction for strength and thermal stability
• Double disc ground braking surface for faster pad bed-in and quieter stops
• Direct OEM replacement — no modification required
• Left (driver) side fitment

The R1 Concepts 623-47042L is a reliable upgrade for drivers seeking improved braking performance over a standard OEM rotor, suitable for daily driving, light street performance, and towing applications.
