Product Details

DFC GEOSPEC rotors are machined to tight tolerances, finished with a non-directional surface for even pad bed-in, and inspected for balance and critical dimensions. The 5000 Advanced pads use ceramic friction material and premium rubber-steel-rubber shims to help control noise, vibration, and harshness. For shoppers searching for rear brake pads and rotors for Genesis G70 or Kia Stinger, part number 4512-21081 provides a direct service-kit solution for the rear axle.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Service Issues

• Rear brake noise, squeal, or vibration
• Rust buildup on rotor surfaces
• Uneven pad wear or reduced braking consistency
• Corroded or fatigued brake hardware
• Longer stopping distances from worn rear components

Installation Notes

Install on the rear axle only. The rotors are shipped dry and ready to install without additional cleaning or oil removal. Follow the vehicle service procedure for pad bedding and inspect caliper hardware, slides, and mounting points during brake service. Confirm exact vehicle configuration before ordering, especially for the 2023 Genesis G70 Brembo brake application.

Quality Assurance

DFC states that each rotor is inspected for critical dimensions and balance, and every rotor carries a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched for consistent friction performance, while the hardware kit is engineered to OE-style form, fit, and function.
