Product Details

The DFC Geoperformance Rotor line focuses on application-specific brake rotor construction for modern passenger vehicles. This rear right rotor uses a directional drilled-and-slotted braking surface to support consistent pad contact and heat management, while the rust resistant coating helps protect exposed surfaces during everyday driving and service intervals. The 284 mm outside diameter, 10 mm nominal thickness, and 76 mm center hole diameter make this rotor a direct-match option for listed Hyundai Sonata, Kia K5, Kia Forte, and related rear brake applications. Part number 830-21014R is also listed for Hyundai Kona, Kia K4, Kia Niro EV, Kia Optima, Hyundai Ioniq, Hyundai Azera, Kia Cadenza, and other confirmed fitments.

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

Installation Notes

Verify rear right position, bolt pattern, center bore, and rotor dimensions before installation. Confirm the vehicle’s brake configuration, especially on applications noted with Electric Parking Brake, and compare the existing rotor thickness against the 10 mm nominal and 8 mm discard specifications. Clean the hub mounting surface before installing the rotor to help maintain proper runout and braking performance. Always follow the vehicle manufacturer’s brake service procedure.
