R1 Concepts 613-40101L RNC Slotted Brake Rotor

The R1 Concepts 613-40101L is a RNC Series slotted brake rotor engineered to deliver consistent, reliable stopping power for everyday street and performance driving. Featuring precision-machined slots across the rotor face, this rotor continuously sweeps debris, gases, and heat away from the pad surface to maintain firm, fade-resistant braking.

Key Features:

• Slotted Design: Machined slots promote continuous pad deglazing and efficient gas and heat evacuation for consistent bite and reduced brake fade
• High-Carbon Gray Iron Construction: Premium casting material provides superior strength, thermal stability, and noise-dampening characteristics
• Zinc Dichromate Coating: Protects non-swept rotor surfaces from corrosion and rust for improved appearance and longevity
• Precision Balanced: Computer-balanced to minimize vibration, pedal pulsation, and steering wheel shimmy
• OE-Style Hat and Vane Configuration: Direct-fit replacement geometry ensures proper caliper clearance and thermal ventilation
• Part Number: 613-40101L (Left / Driver Side)

The R1 Concepts RNC Series slotted brake rotor is a direct OE replacement upgrade, offering improved performance over standard smooth rotors without requiring any modifications. It is sold as a single rotor (left/driver side) and is compatible with factory brake hardware and calipers.
