R1 Concepts 613-39005L RNC Series Slotted Brake Rotor

The R1 Concepts 613-39005L RNC Series Slotted Brake Rotor is a direct-fit performance replacement rotor engineered to deliver superior stopping power and heat dissipation over standard OEM rotors. Designed for drivers who demand more from their braking system, this rotor features precision-machined slots that continuously sweep the brake pad surface to expel heat, gas, and debris during braking.

Key Features:

• Slotted Design: Precision-cut slots improve pad bite, reduce brake fade, and extend pad life by keeping the rotor surface clean and cool
• RNC Series Construction: Manufactured from high-carbon gray iron for excellent thermal stability and consistent performance under repeated hard stops
• Corrosion-Resistant Coating: Non-contact surfaces feature a protective coating to resist rust and maintain a clean appearance
• Direct OE Replacement: Engineered to match original equipment specifications for a hassle-free, no-modification installation
• Balanced and Tested: Each rotor is computer-balanced and meets or exceeds OEM dimensional tolerances for smooth, vibration-free braking
• Left-Side Fitment: This is the driver-side (left) rotor — sold individually

R1 Concepts rotors are manufactured to strict quality standards and offer a performance upgrade over standard replacement rotors, making them an ideal choice for street performance and daily driving applications.
