R1 Concepts 623-31082R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-31082R RNC Series Drilled Brake Rotor is a performance-grade disc brake rotor engineered to deliver improved stopping power and thermal management over standard OE-style rotors. Precision drilled holes across the rotor face allow hot gases and heat to escape rapidly during braking, helping to reduce brake fade and extend pad life under normal and spirited driving conditions.

Manufactured from high-carbon gray iron, this rotor provides excellent rigidity and noise-dampening characteristics. The precision-machined friction surface ensures proper pad seating and even wear, while the factory-balanced design minimizes vibration and pedal pulsation for a smooth, confident braking feel.

Key Features:

• Drilled design evacuates heat, gases, and debris from the rotor surface for consistent braking performance
• High-carbon gray iron construction for superior strength, durability, and reduced rotor cracking
• Precision-machined surface promotes even brake pad wear and smooth pedal feel
• Factory balanced to minimize vibration and brake pulsation
• Corrosion-resistant coating on non-friction surfaces to protect against rust during storage and use
• Direct OE replacement fitment — no modifications required

The R1 Concepts 623-31082R is a direct-fit replacement rotor designed to meet or exceed original equipment specifications. It is compatible with R1 Concepts brake pads as well as most OEM and aftermarket pad compounds for a complete, reliable brake service.
