R1 Concepts 623-28000L RNC Series Drilled Brake Rotor

The R1 Concepts 623-28000L is a drilled replacement brake rotor from R1 Concepts' RNC (Racing and Performance) series. Engineered as a direct OE-style replacement with performance upgrades, this rotor features precision-drilled holes that improve heat dissipation, reduce brake fade, and help expel gas buildup during heavy braking for more consistent, confident stopping power.

Key Features:

• Drilled Pattern: Cross-drilled holes promote rapid heat evacuation and reduce rotor weight for improved braking response
• OE-Style Fitment: Designed to be a direct bolt-on replacement with no modifications required
• High-Carbon Iron Construction: Provides superior durability, noise reduction, and extended service life compared to standard rotors
• Balanced and Tested: Each rotor is precision-balanced to minimize vibration and pedal pulsation
• Corrosion-Resistant Coating: Anti-rust finish protects non-swept surfaces from corrosion during storage and normal use
• Left-Side Application: This is the driver-side (left) rotor — verify vehicle fitment before installation

R1 Concepts brake rotors are manufactured to meet or exceed OEM specifications and are a popular upgrade for drivers seeking improved braking performance over stock components. The RNC series is designed for daily driving and light performance applications where reliability and consistent stopping power are the priority.
