R1 Concepts 613-21021R RNC Series Slotted Brake Rotor

The R1 Concepts 613-21021R is a high-performance slotted brake rotor from the RNC (Race-N-Chrome) Series, engineered for drivers who demand improved stopping power and consistent braking performance. The precision-machined slots continuously sweep the brake pad surface, expelling heat, gas, and debris to maintain a clean contact patch and reduce brake fade under demanding conditions.

Key Features:

• Slotted Design: Strategically machined slots improve bite and help evacuate heat, gas, and dust from the rotor-pad interface
• Race-N-Chrome (RNC) Coating: Proprietary chrome-like coating provides a corrosion-resistant finish and enhanced aesthetics
• Precision Balanced: Each rotor is computer-balanced to minimize vibration and pedal pulsation
• Direct OE Replacement: Designed as a direct bolt-on replacement with no modifications required
• G3000 Grade Cast Iron: High-carbon cast iron construction delivers excellent thermal stability and long service life
• Vented Construction: Internal vane ventilation promotes airflow for rapid heat dissipation

R1 Concepts rotors are manufactured to strict dimensional tolerances, ensuring proper fitment and reliable braking performance. The 613-21021R is the right-side (passenger side) rotor and is sold individually.
