Product Details

The DFC Rotors-Drilled and Slotted-Silver line focuses on performance-oriented braking with OE-spec engineering. For Hyundai Sonata and Kia Optima owners, part number 7004-03055 combines drilled and slotted rotor geometry with precision machining to promote smoother stops, quieter operation, and more even pad contact. This rotor set cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues Addressed

• Excess rotor heat during repeated braking
• Brake pad glazing and uneven pad transfer
• Brake dust and debris buildup on the rotor face
• Vibration or noise caused by inconsistent rotor finish
• Reduced braking bite in wet weather

Installation Notes

Verify rotor size and vehicle build date before installation, especially on 2005-2010 Hyundai Sonata applications with production-date notes. Clean the hub mounting surface, inspect pads and calipers, and follow proper bedding procedures after installation to help the new rotors seat evenly.

Quality Assurance

Each rotor is processed to OE specifications, electronically mill-balanced when required, and inspected for critical attributes before release. DFC backs this rotor set with a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
