R1 Concepts 613-37002L RNC Series Slotted Brake Rotor

The R1 Concepts 613-37002L is a RNC Series slotted brake rotor engineered for drivers seeking improved braking performance and rotor longevity over standard OEM rotors. R1 Concepts designs this rotor with precision-machined slots that continuously sweep the brake pad surface, expelling heat, gas, and debris from the contact zone for more consistent and reliable stopping power.

Key Features:

• Slotted design clears brake dust, gases, and moisture from the pad-to-rotor interface for fade-resistant braking
• Manufactured from high-carbon gray iron for superior heat absorption and dissipation
• Precision-balanced and computer-tested to minimize vibration and pedal pulsation
• Protective electrophoretic (e-coat) coating on non-friction surfaces to resist rust and corrosion during storage and break-in
• Meets or exceeds OEM specifications for a direct, no-modification installation
• Designed for a quiet, low-dust operation suitable for street and performance driving

The R1 Concepts RNC slotted rotor is a direct OEM replacement that delivers a noticeable upgrade in braking feel and thermal performance. It is an ideal choice for daily drivers and enthusiast vehicles that demand reliable, fade-free braking under a variety of conditions.
