• Left Side (Driver's Side): Sold individually as a left/driver-side rotor — verify fitment before ordering
• Corrosion-Resistant Finish: Treated with a zinc or e-coating on non-friction surfaces to resist rust and corrosion during storage and daily use
• Precision Balanced: CNC-machined to tight tolerances to eliminate vibration, pedal pulsation, and noise
• G3000 or Equivalent Grade Steel: Manufactured from high-grade gray iron for durability and consistent thermal performance

R1 Concepts brake rotors are designed for drivers who want a performance upgrade without sacrificing daily driveability. The RNC Series offers an excellent balance of street performance and longevity, making it a smart upgrade for commuters and enthusiasts alike.
