R1 Concepts 633-92109L RNC Series Drilled & Slotted Brake Rotor - Left

The R1 Concepts 633-92109L RNC Series Brake Rotor is a direct-fit, high-performance drilled and slotted replacement rotor designed for drivers seeking improved braking performance over stock. Engineered to replace the driver-side (left) front or rear rotor, this unit delivers superior heat dissipation and consistent stopping power under both everyday driving and spirited conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce heat buildup and expel gas and debris from the rotor surface, while slots sweep away brake dust and water for consistent pad contact
• G3000 Grade Cast Iron: Premium non-directional finish cast iron construction meets or exceeds OEM material standards for durability and long service life
• Zinc Dichromate Coating: Corrosion-resistant coating on non-swept surfaces prevents rust and maintains a clean appearance
• Direct OEM Replacement: Precision-machined to factory specifications for a no-modification, bolt-on installation
• Left Side Fitment: Specifically designed for the driver-side (left) position — verify fitment before ordering
• Balanced & Tested: Each rotor is individually balanced and tested to minimize vibration and ensure smooth, quiet braking performance

R1 Concepts is a trusted name in performance braking components, offering an ideal upgrade for drivers who demand more than stock brake hardware. The RNC drilled and slotted rotor pairs perfectly with R1 Concepts brake pad sets for a complete braking system upgrade.
