R1 Concepts 623-32002L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-32002L RNC Series Drilled Brake Rotor is a performance-grade disc brake rotor engineered to deliver improved stopping power over stock replacements. Designed as a direct-fit, bolt-on replacement, this single rotor (driver's side / left position) is precision-machined to OEM dimensional tolerances for hassle-free installation.

Key Features:

• Cross-Drilled Design: Strategically placed drill holes reduce heat buildup, expel brake dust and gases, and help prevent brake fade during demanding use
• Corrosion-Resistant Coating: Silver zinc coating protects the rotor hub, hat, and vane structure from rust and corrosion, extending service life and maintaining appearance
• OEM-Quality Casting: Manufactured from high-carbon grey iron for consistent friction surface quality, reduced vibration, and quiet operation
• Precision Machined: CNC-balanced to minimize runout and ensure smooth, pulsation-free braking
• Direct-Fit Replacement: Engineered to match factory specifications for straightforward installation — no modifications required
• Single Rotor (Left/Driver Side): Part number suffix "L" designates the left-side position; sold individually

The R1 Concepts RNC Series is suited for daily drivers seeking a reliable performance upgrade over worn or stock rotors. The drilled pattern aids in heat dissipation and rotor cooling, helping to maintain consistent brake pedal feel. Compatible with standard OEM or aftermarket brake pads.
