Keep your rear brakes turning true with the DYNAMIC FRICTION brake rotor (P/N 604-21045, also written 60421045), a GEOSPEC coated disc brake rotor for the rear axle. Designed to meet the same form, fit, and function as OEM brake rotors, it drops in as a direct-fit replacement for the 2020 Hyundai Ioniq and 2020-2022 Kia Niro — see the Buyer's Guide tab for engine-level details.

  • GEOSPEC coating: provides superior corrosion protection over zinc / conventional painting.
  • Premium iron castings: engineered with G3000/G11H18 iron for strength, stability, and durability.
  • Precision machined: CNC-machined to tight tolerances and 100% precision cut and mill-balanced to help deliver smoother stopping and reduced vibration.
  • OE vane configuration: retains the original-equipment vane layout for proper heat dissipation.
  • Non-directional finish: promotes faster break-in and smoother stops, and it's ready to install with no additional pre-degreasing needed.

Quality tested for long-lasting performance. If a worn, warped, or corroded rear rotor is behind your braking complaint, this replaces it. For even, balanced braking, replacing both rear rotors as a matched pair is recommended — this listing is for one rotor, sold individually.

Frequently Asked Questions

Will this DYNAMIC FRICTION brake rotor fit my vehicle?

It's a direct-fit replacement for the 2020 Hyundai Ioniq and 2020-2022 Kia Niro. Check the Buyer's Guide tab to confirm the fit for your exact vehicle.

Is this a front or rear rotor?

This is a rear rotor. It's cataloged for the rear axle of the listed applications.

Do I need to clean or degrease it before installing?

No. It's ready to install with no additional pre-degreasing preparation needed, which saves time during the installation process.

Should I replace both sides at the same time?

For even, balanced braking, replacing both rear rotors as a matched pair is recommended. This listing is for one rotor, sold individually, so order two for a full axle.

What is the GEOSPEC coating?

It's a finish that provides superior corrosion protection over zinc / conventional painting, helping guard the rotor against rust.
