Product Line Details

The DFC Geoperformance Rotor line focuses on performance-oriented brake rotor construction with drilled and slotted surfaces for improved heat management and pad bite characteristics. On applications like the Genesis G70 rear right rotor and Kia Stinger rear right rotor, this format is commonly selected for drivers replacing worn OE-style rotors with a performance-minded direct-fit option.

Fitment

• Fits 2024-2025 Genesis G70, rear right.
• Fits 2022-2023 Genesis G70, rear right. Notes: 4 Piston Front Calipers.
• Fits 2018-2023 Kia Stinger, rear right.
• Fits 2019-2021 Genesis G70, rear right. Notes: Brembo Brakes.

What This Rotor Helps Address

• Rear rotor wear from normal brake use
• Brake pulsation caused by rotor surface irregularity
• Reduced braking consistency from heat buildup
• Corrosion on exposed rotor surfaces
• Replacement needs for drilled and slotted rear brake rotor applications

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear right position before installation. This rotor is directional, so orientation matters during mounting. Confirm caliper configuration and vehicle application details for your Genesis G70 or Kia Stinger before ordering, especially on Brembo brake or 4 piston front caliper vehicles.

Quality Assurance

Dynamite Friction supplies this rotor with a rust resistant coating and a Geospec Silver Grey hat finish to support long-term surface protection and a clean installed appearance. Part number 830-21039R is built to match the listed fitment and dimensional requirements for the specified rear right applications.
