• G3000/G11H18 cast iron rotor construction engineered to OE specifications
• Non-directional rotor finish for more even pad bed-in and smoother braking
• 100% inspected rotors with balance correction on vented designs
• DFC 5000 Advanced Brake Pads with post-cured friction material
• Scorched pads to reduce initial break-in time and improve first-stop response
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control

Product Details

DFC’s GEOSPEC rotor line is built for drivers who want a front brake service kit that matches factory-style fit and finish. The coated rotor surface helps resist rust, while the dry packaging process saves prep time during installation. The 5000 Advanced pads are formulated for stable friction performance and are assembled with shims that help reduce brake noise and vibration.

This part number 4502-03091 is listed for front brake service on 2016-2019 Hyundai Sonata, 2016-2019 Kia Optima, 2018-2019 Kia Optima with 320mm front disc applications, and 2020 Kia Optima. It is also listed for 2016-2017 Hyundai Sonata and 2016-2017 Kia Optima front brake applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or poor pad-to-rotor contact
• Rust buildup on exposed rotor surfaces
• Extended stopping distance from worn friction material
• Uneven braking feel during everyday driving
