R1 Concepts 623-54196R RNC Series Drilled Brake Rotor

The R1 Concepts 623-54196R RNC Series Drilled Brake Rotor is a premium replacement rotor engineered for improved stopping performance and thermal management. Manufactured using high-carbon grey iron, this rotor delivers consistent, fade-resistant braking under both everyday driving and spirited conditions.

The precision cross-drilled holes serve a dual purpose: they help evacuate heat, gas, and brake dust from the rotor face, maintaining a clean contact surface with the brake pad and reducing brake fade during repeated hard stops. The rotor is finished with a non-directional machined surface for proper pad bed-in and even wear.

Key Features:

• Precision cross-drilled rotor design for improved heat and gas dissipation
• High-carbon grey iron construction for strength, durability, and reduced noise
• Electro-coating (e-coat) finish on non-swept surfaces for corrosion resistance
• Precision balanced to minimize vibration and pedal pulsation
• Direct OE replacement — no modifications required for installation
• Manufactured to strict dimensional tolerances for proper fitment and performance

The R1 Concepts RNC Series is an ideal upgrade for drivers seeking reliable, high-quality brake components that outperform standard OEM rotors. This rotor is a direct bolt-on replacement designed for a hassle-free installation.
