R1 Concepts 623-48049L RNC Series Drilled Brake Rotor Left Side

The R1 Concepts 623-48049L is a left-side drilled brake rotor from the RNC (Rotor Non-Coated) Series, engineered for drivers who demand consistent stopping power and reliable thermal management. Precision-drilled holes across the rotor face promote efficient heat dissipation and help evacuate gas, dust, and debris from the rotor surface, maintaining firm, fade-resistant braking under a wide range of driving conditions.

Key Features:

• Drilled Design: Cross-drilled holes improve heat dissipation and help prevent brake fade during sustained or aggressive braking
• Left-Side Fitment: Designed specifically for the driver-side (left) position for precise OEM-style installation
• OE Geometry: Manufactured to OEM specifications for a direct, no-modification-required fit
• High-Carbon Metallurgy: R1 Concepts utilizes a high-carbon iron alloy for improved rotor life, quieter operation, and reduced vibration
• Balanced Performance: Suitable for daily driving and spirited street use, delivering responsive pedal feel and smooth braking
• Corrosion-Resistant Finish: Non-coated rotor surface with corrosion-resistant hat and edges to maintain appearance out of the box

The R1 Concepts 623-48049L is a direct replacement brake rotor that pairs seamlessly with a wide range of brake pads and caliper setups. For best results, replace both left and right rotors as a matched pair and bed in pads according to R1 Concepts' recommended break-in procedure.
