R1 Concepts 613-31105L RNC Series Slotted Brake Rotor

The R1 Concepts 613-31105L RNC Series Slotted Brake Rotor is a direct-fit performance replacement rotor engineered to deliver improved stopping power and consistent brake feel. Machined from high-grade G3000 cast iron, this rotor meets or exceeds OEM specifications while offering the added benefit of a slotted surface design.

The slotted rotor face continuously sweeps brake pad gases, heat, and debris away from the contact surface, helping to maintain a clean bite zone, reduce brake fade, and extend pad life. The rotor is finished with a corrosion-resistant coating on the non-braking surfaces to resist rust and protect against the elements.

Key Features:

• Slotted rotor design for improved heat dissipation and gas venting
• Manufactured from G3000 grade cast iron for strength and thermal stability
• Corrosion-resistant coating on hat and non-friction surfaces
• Precision machined to strict OEM dimensional tolerances
• Direct OE replacement — no modifications required for installation
• Designed for street performance and daily driving applications
• FMSI / OEM cross-reference engineered for proper fit and function

The R1 Concepts RNC slotted rotor is an ideal upgrade for drivers seeking better brake response and longer-lasting performance compared to a standard smooth rotor replacement.
