R1 Concepts 623-27026L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-27026L RNC Series Drilled Brake Rotor is a precision-engineered replacement disc rotor designed to deliver consistent, reliable stopping performance. Manufactured from high-quality G3000 grade cast iron, this rotor meets or exceeds OEM dimensional and metallurgical specifications for a direct bolt-on fit.

The drilled pattern across the rotor face serves a dual purpose: reducing overall rotor weight and allowing heat, gas, and water to evacuate quickly from the braking surface. This results in improved brake pad bite, reduced brake fade under repeated stops, and enhanced wet-weather braking performance.

Key Features:

• Drilled rotor design for improved heat dissipation and reduced fade
• G3000 grade cast iron construction for strength and longevity
• Zinc-coated hat and non-braking surfaces to resist corrosion and rust
• Precision machined to OEM tolerances for smooth, vibration-free braking
• Direct OEM replacement — no modifications required for installation
• Left-side (driver-side) application

R1 Concepts rotors are manufactured under strict quality control standards and are designed as a direct replacement for worn or damaged factory brake rotors. This rotor is sold individually and is intended for the left (driver) side of the vehicle.
