R1 Concepts 613-20003L RNC Series Slotted Brake Rotor

The R1 Concepts 613-20003L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver consistent, fade-resistant stopping power for demanding street and performance driving conditions. The slotted rotor design continuously cleans and deglazes brake pads during use, improving bite and maintaining stable performance under repeated hard braking.

Key Features:

• Slotted Design: Precision-machined slots evacuate heat, gas, and debris from the rotor face, keeping the braking surface clean and responsive
• Improved Pad Bite: Slots provide consistent pad bite and reduce glazing for more predictable, linear brake response
• High-Carbon Gray Iron Construction: Premium metallurgy for excellent thermal dissipation and rotor longevity
• Direct OE Replacement: Engineered to match OEM fitment specifications for straightforward installation without modification
• Zinc Dichromate Coating: Corrosion-resistant coating on non-swept surfaces helps prevent rust and extends rotor life
• Balanced and Tested: Each rotor is precision-balanced and inspected for runout and thickness variation before leaving the factory

The R1 Concepts RNC line is designed for drivers seeking a meaningful upgrade over standard OEM rotors without sacrificing daily drivability. This left-side (driver side) rotor is sold individually and is compatible with its matching right-side counterpart for a complete front or rear axle replacement.
