Built for smooth rear stopping, the Dynamic Friction Company GEOSPEC Coated Rotor, part number 604-21014, is a blank-style rear brake rotor CNC-machined to the tightest tolerances. It fits many vehicles, among them the 2015-2026 Hyundai Sonata, 2013-2020 Kia Optima and 2024-2026 Hyundai Kona, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.

  • Precision machining: 100% precision cut and mill-balanced, designed for smoother stopping and to help minimize vibration.
  • OE vane configuration: follows the original equipment vane configuration, intended for proper heat dissipation.
  • Iron castings: made with premium G3000/G11H18 iron castings for strength, stability and durability.
  • GEOSPEC coating: DFC rates its corrosion protection above zinc or conventional painting.

A non-directional finish promotes faster break-in and smoother stops, and each rotor is quality tested. DFC designs it to meet the same form, fit and function as OEM brake rotors. It arrives ready to install, and no additional pre-degreasing preparation is needed, which saves time during the brake job. Replacing both rotors on the same axle together as a matched pair is recommended for even, balanced braking.

Frequently Asked Questions

Is this a rear Hyundai Sonata brake rotor?

Yes. It is listed as a rear rotor for the 2015-2026 Hyundai Sonata. The Buyer's Guide tab shows every listed application.

Will it work as a Kia Optima brake rotor?

Yes. It is listed for the rear of the 2013-2020 Kia Optima. It also fits many other Hyundai and Kia models shown in the Buyer's Guide tab.

What does a disc brake rotor do?

The brake pads clamp against the spinning rotor and turn the vehicle's motion into heat to slow it down. This rotor's OE vane configuration is intended to help dissipate that heat.

Do I need to degrease the rotor before installing it?

No. DFC states it is ready to install with no additional pre-degreasing preparation needed. Follow your vehicle's service information for mounting and torque procedures.

What are signs rear rotors may need replacing?

Common signs include pulsation when braking, grinding noises, and deep scoring or grooves on the rotor face. Replacing both rear rotors together is recommended for even, balanced braking.
