R1 Concepts 631-31184D RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-31184D RNC Series Drilled & Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power, improved heat dissipation, and consistent fade resistance under demanding driving conditions. Designed as a direct OEM replacement, this rotor installs without modification for a straightforward upgrade.

R1 Concepts' drilled and slotted design combines two proven performance technologies: cross-drilled holes reduce rotor weight and allow gases, heat, and debris to escape from the braking surface, while machined slots continuously clean and refresh the brake pad surface, maintaining consistent bite throughout the life of the rotor.

Key Features:

• Drilled and slotted rotor design for enhanced performance and cooling
• Precision-machined from premium G3000 grade iron casting for durability and consistent braking
• Zinc dichromate coating on non-friction surfaces to resist rust and corrosion
• Balanced and tested to minimize vibration and brake pedal pulsation
• Direct OEM replacement — no modifications or adapters required
• Meets or exceeds OEM specifications for a safe, reliable fit

Whether used for daily driving or spirited performance applications, the R1 Concepts RNC rotor is an ideal upgrade over worn or stock rotors, delivering improved feel and longevity. Sold individually — verify quantity needed for your application.
