R1 Concepts 623-32013L RNC Series Drilled Brake Rotor

The R1 Concepts 623-32013L is a precision-engineered drilled brake rotor from R1 Concepts' RNC (Drilled) Series, designed as a direct OE replacement upgrade for improved braking performance. Manufactured from high-quality G3000-grade cast iron, this rotor delivers consistent stopping power and excellent heat dissipation under both everyday street driving and spirited driving conditions.

Key Features:

• Drilled design — cross-drilled holes promote cooling airflow, reduce brake fade, and help expel gas and debris from the rotor surface
• G3000 grade cast iron — OEM-equivalent metallurgy ensures durability, minimal vibration, and quiet operation
• Zinc dichromate coating — corrosion-resistant finish protects non-swept surfaces from rust and extends rotor life
• OE-matched geometry — direct bolt-on fitment with no modifications required
• Precision balanced — computer-balanced to eliminate vibration and pedal pulsation
• Left-side (driver's side) rotor — designated by the "L" suffix in the part number

R1 Concepts rotors are manufactured to strict dimensional tolerances and undergo rigorous quality control testing. The 623-32013L is sold as a single rotor and is engineered to pair perfectly with OEM or aftermarket brake pads for a reliable, confident braking experience.
