R1 Concepts Drilled Slotted Brake Rotor RNC Series Performance Disc

The R1 Concepts RNC Series Drilled and Slotted Brake Rotor is a performance disc brake rotor made as a direct-fit replacement for factory rotors. It is meant for drivers who want better stopping performance and heat management than a plain OEM rotor gives, without moving to a full big-brake kit. The cross-drilled and slotted surface pattern suits daily driving, spirited street use, and light performance use.

Key Features:

• Drilled and slotted design: The drilled holes help move heat, gas, and water away from the rotor face. The slots sweep the pad surface clean to resist glazing and help keep pad bite consistent.
• Better heat management: The pattern helps reduce brake fade and improves wet-weather braking.
• High-carbon cast iron construction: G3000-grade metallurgy gives durability, consistent performance, and reduced noise compared with standard cast iron.
• Corrosion-resistant coating: A zinc-based coating on the hat and other non-friction surfaces resists rust in storage and in service, and keeps the rotor looking clean.
• Precision machined and balanced: Built to OE tolerances for smooth braking with minimal vibration and pedal pulsation.
• Direct OE-style fit: Matches factory mounting dimensions for bolt-on installation with no modifications.

Each rotor is sold under its own part number for a specific position, so choose the part number that matches your application. As the coating on the swept friction surfaces wears off during pad bedding, the rotor settles into normal use. The RNC Series is a practical upgrade for drivers who want improved braking feel and longer rotor life.
