R1 Concepts RNC Drilled Slotted Performance Brake Rotor

The R1 Concepts RNC Drilled and Slotted Performance Brake Rotor line gives drivers a direct-fit upgrade over standard OEM disc brake rotors. Each rotor combines cross-drilled holes with machined slots. The pattern improves heat management, stopping consistency and wet-weather braking. It suits daily driving, spirited street use and light performance applications.

Key Features:

• Drilled and slotted surface: The holes help vent heat, gas and water from the rotor face. The slots sweep the pad surface clean and help prevent glazing.
• Better fade resistance: Improved heat dissipation helps keep braking performance consistent under demanding conditions.
• Corrosion-resistant coating: A protective zinc-based coating on the hat and other non-swept areas resists rust and helps the rotor keep its appearance. The friction surface wears to bare metal as the rotor beds in.
• Direct OE-style replacement: Matches factory mounting design for bolt-on installation with no modifications.
• Precision machined and balanced: Built to tight tolerances to reduce vibration and pedal pulsation and to support quiet, smooth braking.

For best results, follow a proper bed-in procedure after installation. This transfers an even layer of pad material to the rotor surface. Pair these rotors with quality brake pads. The RNC series is a good fit for drivers who want better braking performance and rotor life without moving to a full big-brake kit.
