R1 Concepts 613-27012L RNC Series Slotted Brake Rotor

The R1 Concepts 613-27012L is a left-side slotted brake rotor from the RNC Series, engineered to deliver consistent stopping power and improved thermal performance over standard OEM rotors. Slotted rotors feature machined grooves across the rotor face that continuously sweep the brake pad surface clean of gas, dust, and debris — helping maintain a fresh contact edge for more reliable, fade-resistant braking.

Key Features:

• Slotted Design: Slots vent heat and expel gas buildup, reducing brake fade under repeated or heavy braking conditions
• OEM-Equivalent Fitment: Engineered to direct-fit OEM mounting specs for a straightforward installation with no modifications required
• Left Side (Driver Side): This rotor is specifically designed for the left/driver-side wheel position
• Balanced Performance: Ideal for daily drivers and enthusiasts seeking improved braking feel over stock rotors without the harshness of fully drilled designs
• Precision Machined: Manufactured to tight tolerances to minimize runout and ensure smooth, vibration-free braking
• Corrosion-Resistant Finish: Non-braking surfaces are coated to resist rust and corrosion for a cleaner appearance and longer service life

The R1 Concepts RNC slotted rotor is a reliable upgrade for drivers looking to improve braking consistency, pedal feel, and rotor longevity. Always replace rotors in axle pairs and inspect brake pads at time of installation.
