R1 Concepts 631-92070L RNC Drilled & Slotted Brake Rotor

The R1 Concepts 631-92070L RNC Series Drilled and Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver superior stopping power and thermal management over stock brake components. Designed for drivers who demand more from their braking system, this rotor combines precision machining with proven performance design.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes and milled slots work together to dissipate heat rapidly, expel gas and debris from the rotor surface, and reduce brake fade during demanding use
• Precision Machined: Computer-balanced construction minimizes vibration and pedal pulsation for a smooth, confident braking feel
• OE-Style Hub Dimensions: Direct bolt-on fitment with no modifications required for compatible vehicles
• Corrosion-Resistant Finish: Protective coating applied to non-friction surfaces helps resist rust and extend rotor service life
• Improved Pad Bite: The slotted surface continuously cleans and deglazes brake pads, maintaining consistent bite and responsiveness

The R1 Concepts RNC series is ideal for performance street driving and light track use, offering a meaningful upgrade over standard OEM rotors. Sold as a single rotor (left side). Always replace brake rotors in axle pairs for balanced braking performance.
