R1 Concepts 633-28000L RNC Series Drilled & Slotted Brake Rotor - Left

The R1 Concepts 633-28000L is a RNC Series Drilled and Slotted Brake Rotor engineered for drivers who demand reliable, high-performance stopping power. Manufactured from premium G3000-grade cast iron, this rotor delivers consistent, fade-resistant braking under a wide range of driving conditions.

The combined cross-drilled and slotted surface pattern works to dissipate heat rapidly, channel away gas and debris from the pad surface, and reduce brake fade during spirited or demanding driving. The slotted grooves continuously clean and refresh the brake pad contact surface for optimal bite and consistent pedal feel.

Key Features:

• Drilled and slotted rotor design for superior heat dissipation and reduced brake fade
• G3000-grade cast iron construction for durability and consistent performance
• Zinc-plated hat and non-braking surfaces for corrosion resistance
• Left-side (driver side) specific fitment — part of a matched rotor pair
• Direct OE-replacement fit — no modifications required for installation
• Precision balanced and computer-optimized for vibration-free operation
• Compatible with OEM and performance aftermarket brake pads

The 633-28000L is sold as a single rotor (left/driver side) and is designed to be used as a direct replacement or as part of a complete brake upgrade.
