R1 Concepts 613-31181D RNC Series Slotted Brake Rotor

The R1 Concepts 613-31181D RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver improved stopping power and heat dissipation over standard OEM rotors. Precision-machined from premium G3000 gray iron casting, this rotor is built to OEM and beyond specifications for reliable, consistent braking performance.

The slotted rotor design features precision-cut slots across the rotor face that continuously wipe the brake pad surface clean, expelling gas, heat, and debris from the contact zone. This improves pad bite, reduces brake fade under demanding conditions, and extends overall pad life.

Key Features:

• Slotted rotor design for improved pad bite and heat venting
• Manufactured from premium G3000 gray iron for strength and durability
• Precision CNC machined to strict dimensional tolerances
• Zinc dichromate coating on non-friction surfaces helps resist rust and corrosion
• Balanced and tested to minimize vibration and pedal pulsation
• Direct OEM replacement — no modifications required for installation
• Meets or exceeds OE specifications for safe, reliable stopping

R1 Concepts rotors are engineered for enthusiast drivers who demand more than a standard blank rotor can offer. The RNC slotted series is an excellent upgrade for street performance, towing, and spirited driving applications where consistent brake performance is critical.
