R1 Concepts 613-32020R RNC Series Slotted Brake Rotor

The R1 Concepts 613-32020R RNC Series Slotted Brake Rotor is a high-performance direct-fit replacement rotor engineered for drivers who demand improved stopping power and fade resistance over standard OEM rotors. Machined from premium G3000 grey iron casting, this rotor delivers consistent, reliable braking performance under both everyday driving and demanding conditions.

The slotted rotor design continuously sweeps the brake pad surface to expel heat, gas, and debris from the rotor face, reducing brake fade and maintaining firm, consistent pedal feel. The slots also help keep brake pads properly conditioned and prevent glazing over time.

Key Features:

• Slotted rotor design for improved heat dissipation and gas evacuation
• Manufactured from G3000 high-carbon grey iron for strength and thermal stability
• Precision computer-balanced to minimize vibration and brake pedal pulsation
• Zinc dichromate anti-rust coating on non-friction surfaces to resist corrosion during storage and use
• Direct OEM replacement — no modifications required for installation
• Meets or exceeds OEM dimensional specifications for proper fitment and performance
• Rotor vanes designed for optimal airflow and cooling efficiency

The R1 Concepts RNC line offers an accessible upgrade path from standard rotors, providing slotted performance benefits at a competitive price point. Whether used as a daily driver upgrade or a street performance enhancement, the 613-32020R is a dependable choice for improved braking confidence.
