Product Details

DFC’s GEOSPEC rotor and 5000 Advanced pad pairing is engineered for front brake service on vehicles such as the Hyundai Sonata, Hyundai Kona Electric, Kia Optima, and Kia Niro EV. The coated rotors resist rust better than conventional painted or zinc-coated finishes, while the dry packaging and ready-to-install surface help reduce prep time during brake work. Part number 4502-03171 is a practical choice for a front brake job that needs matched components in one kit.

The pad compound is post cured for stable friction performance and scorched to remove uncured bonding agents, helping deliver consistent stopping response from the first stop. DFC also uses premium rubber-steel-rubber shims to help control brake noise, vibration, and harshness.

Installation Notes

Install on the front axle only. Confirm rotor size, parking brake configuration, and trim-specific brake requirements before ordering, especially on Hyundai Sonata and Kia Optima applications with manual or electric parking brake notes. Clean the hub surface before installation and follow the vehicle manufacturer’s torque and bedding procedures for proper brake performance.

Quality Assurance

Each rotor is machined to tight tolerances, inspected for critical dimensions, and checked for balance on vented designs. DFC states that every rotor is inspected to meet OE specifications, and the rotors include a 12-month warranty against defects in material and workmanship. Part number 4502-03171 is backed by that rotor warranty coverage as supplied in the kit.
