R1 Concepts 613-39000L RNC Slotted Brake Rotor - Left Side

The R1 Concepts 613-39000L RNC Slotted Brake Rotor is a direct-fit, performance-oriented disc brake rotor engineered to deliver improved stopping power and extended service life over standard OEM rotors. Designed as a left-side replacement, this rotor slots directly into your factory braking system for a straightforward installation.

Key Features:

• Slotted Rotor Design: Precision-machined slots channel heat, gases, and brake dust away from the pad surface, reducing brake fade and preventing pad glazing during repeated stops
• Left-Side Fitment (L): Engineered specifically as a driver-side or left-side rotor for precise fitment and proper directional performance
• Corrosion-Resistant Coating: Protective zinc-plated coating on the non-braking surfaces helps guard against rust and corrosion, improving longevity and appearance
• Precision Balanced Construction: Manufactured to tight tolerances to minimize vibration, pedal pulsation, and noise during braking
• Direct OEM Replacement: Designed to match original equipment dimensions and bolt patterns for hassle-free installation without modifications
• High-Carbon Iron Alloy: Cast from high-quality iron for excellent thermal capacity and consistent braking performance across a wide temperature range

The R1 Concepts RNC series slotted brake rotor is a reliable upgrade for drivers seeking better braking response than standard blank rotors, making it well-suited for daily driving, light performance use, and vehicles that demand dependable stopping power. A proper brake bed-in procedure is recommended after installation for optimal performance.
