What It Is Used For

• Replacing a worn front left rotor on a Genesis G70 or Kia Stinger
• Restoring braking surface thickness after rotor wear
• Addressing brake pulsation caused by rotor variation
• Replacing a rotor with scoring, heat checking, or surface corrosion
• Maintaining proper brake contact on Brembo and 4 piston front caliper setups

Installation Notes and Tips

Verify rotor diameter, thickness, bolt pattern, and front left position before installation. Confirm caliper type and vehicle year against the listed fitment: Fits 2022 Genesis G70, front left, with 4 piston front calipers; Fits 2019-2021 Genesis G70, front left, with Brembo brakes; Fits 2018-2022 Kia Stinger, front left. Clean the hub mounting surface before installing the rotor and inspect pads and caliper hardware for wear at the same time. Part number 830-21038L should be matched to the exact application shown above.
