• Rotor scoring or uneven braking surface condition
• Corrosion on the rotor hat area
• Brake pulsation related to a worn front left rotor
• Replacement needs for drilled and slotted vented rotor applications

Installation Notes

Verify rotor diameter, thickness, center hole diameter, and bolt pattern before installation. This rotor is directional, so confirm left-side orientation and match the slot pattern to the vehicle position. For 2017-2022 Kia Sportage and 2015-2019 Hyundai Sonata applications, confirm the Electric Parking Brake configuration before ordering. Always inspect pads, caliper condition, and hub surface during brake service.

Quality Assurance

Dynamic Friction supplies application-specific brake components for direct-fit replacement use. This rotor includes a rust resistant coating and a Geospec Silver Grey hat finish for added surface protection on the hub area.
