Product Line Details

The DFC GEOSPEC Coated Rotors line is designed to resist rust with a silver-gray protective coating and arrives dry, so there is no need to clean off oil before installation. The 5000 Advanced Brake Pads line uses post-cured and scorched friction material to promote stable braking performance from the first stop. Together, these components are paired with hardware engineered to OE-style form, fit, and function.

Installation Notes

Rear brake service on these Kia and Hyundai applications is simplified by the dry rotor finish, which eliminates rotor prep before installation. The non-directional rotor finish supports quicker pad bed-in, and the included hardware is intended to replace fatigued or corroded brake hardware during service. Verify the vehicle year, model, and any listed notes such as 5 lug wheels or production date cutoffs before ordering.

Quality Assurance

Each DFC GEOSPEC rotor is machined to tight tolerances, inspected for balance on vented designs, and checked against OE specifications after machining. The rotors carry a 12-month warranty against defects in material and workmanship. The brake pads are post cured and scorched for stable friction performance, and the hardware kit is built to OE-style form, fit, and function.
