R1 Concepts RNC Drilled Slotted Disc Brake Rotor

The R1 Concepts RNC Drilled and Slotted Disc Brake Rotor line is a performance-oriented replacement brake rotor. It is built to improve stopping performance and heat management compared with standard plain-surface OEM rotors. Each rotor combines cross-drilled holes with machined slots, so it works as a direct-fit upgrade for daily driving, spirited street use, and light track use.

Key Features:

• Drilled and slotted design: The drilled holes help vent heat, gas, and water from the rotor face. The slots sweep the pad surface clean to help prevent glazing and keep pad bite consistent.
• Reduced brake fade: Better heat dissipation helps maintain braking performance under demanding conditions.
• Improved wet-weather braking: The drilled and slotted surface helps clear water and debris from the pad contact area.
• Corrosion-resistant coating: A protective coating on the hat and non-friction surfaces resists rust and keeps the rotor looking good. The braking surface wears to bare metal during bed-in.
• Quality cast iron construction: Durable, high-carbon grey iron metallurgy provides strength, thermal capacity, and reduced noise.
• Precision machined and balanced: Tight tolerances help give smooth, vibration-free braking with less pedal pulsation.
• Direct OE-style replacement: The rotors match factory mounting dimensions for bolt-on installation without modification.

R1 Concepts RNC rotors give drivers a straightforward upgrade over stock rotors. They offer better braking feel, heat control, and rotor life, and they work with a wide range of OEM-style brake pads. Choose the correct part number for your application from the options listed on this page.
