R1 Concepts 623-40061L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-40061L RNC Series Drilled Brake Rotor is a direct OE-replacement rotor engineered to deliver improved stopping performance and long-lasting durability. Designed as a left-side (driver's side) replacement, this rotor is precision-machined to exact OEM specifications for a proper fit and confident braking feel.

R1 Concepts' RNC (Rust & Noise Control) line features a proprietary coating process that protects non-friction surfaces from rust and corrosion, helping to keep the rotor looking clean while reducing brake noise and vibration. The drilled pattern promotes heat dissipation and helps evacuate gas and water from the rotor face, maintaining consistent pad contact under demanding conditions.

Key Features:

• Drilled Design: Cross-drilled holes help reduce heat buildup and improve wet-weather braking performance
• RNC Coating: Rust & Noise Control coating on non-friction surfaces resists corrosion and minimizes brake noise
• OEM-Matched Specifications: Precision machined to factory dimensions for a direct bolt-on fitment
• Balanced Performance: Engineered for use with OEM or performance brake pads
• Left Side (Driver's Side): This listing is for the left/driver's side rotor only
• Vented Construction: Internal vane design promotes airflow and thermal management

The R1 Concepts 623-40061L is an excellent upgrade or direct replacement for worn OEM rotors, offering enhanced corrosion protection and a cleaner appearance without sacrificing everyday drivability.
