R1 Concepts 623-31024L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-31024L RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver confident, consistent stopping power. Featuring a drilled rotor design, this rotor promotes improved heat dissipation and helps reduce brake fade during repeated or heavy braking cycles, making it a popular upgrade over standard solid OEM rotors.

Key Features:

• Drilled Design: Cross-drilled holes allow heat and gases to escape from the rotor surface, reducing thermal buildup and maintaining consistent brake performance
• Left-Side Fitment: Specifically designed for the driver's side (left) application — part of a direct-fit replacement pair
• Precision Balanced: CNC-machined to tight tolerances for smooth, vibration-free braking and proper pad seating
• Corrosion-Resistant Finish: Treated with a zinc or e-coating on non-friction surfaces to resist rust and corrosion during storage and service life
• Direct OE Replacement: Engineered to match original equipment specifications for straightforward, no-modification installation
• Premium Grade Iron: Cast from high-carbon iron for superior thermal capacity and long rotor life

The R1 Concepts RNC Series is designed for drivers seeking a performance-oriented upgrade that retains daily-driver reliability. This rotor installs using factory mounting hardware and is compatible with OEM and aftermarket brake pads. MPN: 623-31024L.
