R1 Concepts 631-92027R RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92027R RNC Series Drilled and Slotted Brake Rotor is a direct-fit performance upgrade engineered to deliver improved stopping power and thermal management over standard OEM rotors. Manufactured to strict dimensional tolerances, this rotor installs in place of the factory unit without modification.

The drilled and slotted surface pattern works together to evacuate heat, gas, and debris from the rotor face during braking. Drilling reduces overall rotor mass and helps dissipate heat rapidly, while the slots continuously sweep the brake pad surface clean for consistent bite and reduced fade under repeated hard braking.

Key Features:

• Drilled and slotted rotor design for enhanced heat dissipation and bite
• Direct OEM replacement — no modifications required for installation
• Precision machined to ensure proper balance and runout specifications
• High-carbon iron construction for durability and fade resistance
• Protective coating on non-friction surfaces to resist rust and corrosion during storage and break-in
• Sold individually (single rotor)

The R1 Concepts RNC Series is an ideal choice for drivers seeking a measurable performance improvement over worn or stock rotors while maintaining street-legal daily driveability. Compatible with OEM-style caliper and bracket hardware.
