R1 Concepts 623-27005L RnC Drilled Brake Rotor Left Front/Rear

The R1 Concepts 623-27005L RnC Drilled Brake Rotor is a direct OEM-style replacement rotor engineered for consistent stopping performance and long service life. Designed as a left-side (driver side) application, this rotor slots seamlessly into your existing brake system without modification.

R1 Concepts' RnC (Replace and Continue) line is built for drivers who want a reliable, high-quality OEM replacement with enhanced cooling characteristics. The precision-drilled holes improve heat dissipation, reduce brake fade during repeated stops, and help expel gas and debris from the rotor surface for more consistent pad contact.

Key Features:

• Drilled hole pattern for improved heat dissipation and reduced brake fade
• Left-side (driver side) direct-fit replacement — no modification required
• Manufactured from high-carbon grey iron for durability and noise reduction
• Precision-machined to strict OEM tolerances for proper fitment and smooth operation
• Zinc dichromate coating on non-contact surfaces to resist corrosion during storage and service
• Balanced and tested to minimize vibration and pedal pulsation

The R1 Concepts RnC rotor is an ideal upgrade or replacement for worn or warped OEM rotors, delivering dependable braking performance for daily driving and light performance use.
