R1 Concepts 613-40049R RNC Series Slotted Brake Rotor

The R1 Concepts 613-40049R RNC Series Slotted Brake Rotor is a performance-engineered replacement rotor designed to deliver improved braking performance over standard OEM rotors. R1 Concepts manufactures their RNC rotors using high-grade G3000 cast iron for excellent thermal conductivity, durability, and consistent pedal feel under a wide range of driving conditions.

The slotted design features precision-machined slots across the rotor face that continuously clean and deglaze brake pads during operation, helping to maintain optimal pad bite and reduce brake fade during spirited or demanding driving. The slots also assist in venting heat and gases away from the braking surface, contributing to more consistent stopping performance.

Key Features:

• Slotted rotor design for improved pad deglazing and heat dissipation
• G3000 high-carbon cast iron construction for strength and thermal stability
• Precision machined to OEM dimensional specifications for direct bolt-on fitment
• Electrostatic zinc coating on non-friction surfaces to resist corrosion and rust
• Balanced for smooth, vibration-free braking performance
• Direct replacement for OEM rotors — no modifications required

R1 Concepts rotors are manufactured to meet or exceed OEM standards and are a popular upgrade for drivers seeking improved braking response without the complexity of a full big brake kit. The 613-40049R is the right-side (passenger side) rotor, so confirm your application before ordering.
