R1 Concepts 613-39021R RNC Series Slotted Brake Rotor

The R1 Concepts 613-39021R RNC Series Slotted Brake Rotor is a performance-grade replacement rotor engineered for drivers who demand consistent, fade-resistant stopping power. Manufactured to precise OEM dimensional tolerances, this rotor installs as a direct replacement with no modifications required.

Key Features:

• Slotted Surface Design: Machined slots continuously sweep debris, gas, and heat away from the rotor face, maintaining a clean pad contact surface and reducing brake fade under repeated or heavy braking
• OEM-Equivalent Fitment: Engineered to meet or exceed original equipment specifications for a straightforward, hassle-free installation
• High-Carbon Iron Casting: Premium iron alloy construction provides superior heat dissipation and long-term rotor durability
• Precision Balanced: Each rotor is computer balanced to minimize vibration and pedal pulsation for a smooth, confident braking feel
• Corrosion-Resistant Finish: Non-braking surfaces are coated to resist rust and maintain a clean appearance

The R1 Concepts RNC line bridges the gap between everyday street use and spirited driving demands, making the 613-39021R an ideal upgrade for drivers seeking improved braking performance over worn or stock rotors.
