R1 Concepts 633-92094L RNC Series Drilled & Slotted Brake Rotor - Left

The R1 Concepts 633-92094L is a RNC Series cross-drilled and slotted brake rotor engineered for drivers who demand enhanced stopping performance over stock replacements. Featuring a combination of precision drilled holes and machined slots, this rotor promotes aggressive heat dissipation, gas evacuation, and consistent pad bite under demanding braking conditions.

Key Features:

• Cross-Drilled Holes: Reduce rotor temperature by allowing heat and gases to escape, minimizing brake fade during repeated hard stops
• Machined Slots: Continuously clean and deglaze the brake pad surface for consistent friction and improved wet-weather braking performance
• Silver Zinc Plating: Corrosion-resistant zinc coating on the hat and non-swept surfaces protects against rust and extends rotor life
• High-Carbon Cast Iron Construction: Provides superior strength, durability, and thermal stability compared to standard grey iron rotors
• Left-Side Fitment (L): Designed specifically for the driver-side position for proper directional slot orientation and precise fit
• Direct OE Replacement: Bolt-on installation with no modifications required; matches original mounting specifications

The R1 Concepts RNC Series rotor is a performance upgrade over stock rotors, offering improved thermal management and braking consistency for street and light performance driving. Each rotor is individually packaged and ready for installation.
