R1 Concepts 631-92012R RNC Series Drilled & Slotted Brake Rotor

The R1 Concepts 631-92012R RNC Series Brake Rotor is a premium drilled and slotted performance rotor engineered to deliver superior stopping power and fade resistance over stock replacement rotors. Designed as a direct OE-style fitment, this rotor installs without modification for a straightforward upgrade from your factory brake setup.

R1 Concepts' RNC Series rotors feature a precision-machined rotor face with cross-drilled holes and milled slots that work together to continuously sweep brake dust and gases away from the pad surface. This keeps the rotor and pad interface clean and consistent, maintaining firm pedal feel during repeated or aggressive braking.

Key Features:

• Drilled and slotted rotor face for improved heat dissipation and pad degassing
• Precision CNC-machined to strict dimensional tolerances for smooth, vibration-free operation
• Zinc dichromate coating on non-friction surfaces to resist corrosion and enhance appearance
• Vented rotor construction promotes airflow for thermal management during heavy use
• Direct OE replacement — no modifications or adapter hardware required
• Manufactured to meet or exceed OEM specifications for runout and thickness variation

The R1 Concepts RNC Series is an ideal choice for drivers seeking a reliable performance upgrade that combines enhanced braking response with long rotor life. Compatible with both OEM and aftermarket performance brake pads.
