R1 Concepts 623-26005L RNC Series Drilled Brake Rotor

The R1 Concepts 623-26005L RNC Series Drilled Brake Rotor is a precision-engineered replacement brake rotor designed to deliver consistent stopping power and improved thermal performance. R1 Concepts manufactures their rotors from high-carbon gray iron, which provides superior heat dissipation and reduces the risk of brake fade during demanding driving conditions.

The drilled pattern across the rotor face serves a dual purpose: it allows heat, gas, and moisture to escape quickly from the braking surface, maintaining consistent contact between the pad and rotor while also reducing overall unsprung weight. Each rotor is precision balanced and features a non-directional finish on the braking surface for optimal pad break-in.

Key Features:

• Drilled rotor design for improved heat and gas venting
• High-carbon gray iron construction for durability and fade resistance
• Precision balanced for smooth, vibration-free braking
• Non-directional surface finish promotes even pad seating
• Corrosion-resistant coating on non-braking surfaces
• Direct OE replacement — no modifications required for installation
• Manufactured to meet or exceed OEM specifications

The R1 Concepts RNC Series rotor is an excellent upgrade or direct replacement for drivers seeking improved braking response and longevity over standard OEM rotors. Installation is straightforward with standard hand tools, making it a popular choice for both DIY enthusiasts and professional technicians.
