Dynamite Friction 7002-21031 Disc Brake Rotor Set - Rear

Drilled and Slotted Rear Brake Rotors

Dynamite Friction DFC Brake Rotors - Drilled and Slotted - Silver, part number 7002-21031, are rear disc brake rotors built for drivers who want OE-style fitment with added performance features. The drilled and slotted design helps improve pad bite, shed heat, and clear debris from the braking surface.

Compatible With rear brake applications on select Hyundai Kona Electric, Kia Niro EV, and Kia Cadenza models, these rotors are machined to tight tolerances for consistent braking feel. The silver GEOSPEC coating helps protect the rotor surface while supporting clean, quiet operation.

Key Features

• Drilled holes help reduce heat buildup during repeated braking
• Slots clear brake dust and road debris from the rotor face
• Non-directional finish supports faster, more even pad bed-in
• Machined to OE-style specifications for fit, durability, and stability
• 100% inspected for balance and critical dimensions
• Silver-coated finish for added corrosion resistance on exposed surfaces

Product Details

The DFC Brake Rotors - Drilled and Slotted - Silver line is built around performance-oriented rotor geometry with OE-matching construction standards. For part number 7002-21031, the G3000/G11H18 cast iron specification, precision machining, and electronic mill-balancing process are used to deliver consistent rear braking performance. This rotor set is a direct-fit option for drivers searching for rear brake rotors for 2022-2023 Hyundai Kona Electric, 2019-2022 Kia Niro EV, 2019-2021 Hyundai Kona Electric, or 2017-2020 Kia Cadenza rear applications.

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

What It Helps Address

• Brake fade from heat buildup in repeated stops
• Reduced pad bite on wet or debris-covered roads
• Brake dust and road contamination on the rotor surface
• Uneven pad transfer or glazing
• Noise and vibration caused by inconsistent rotor finish

Installation Notes and Tips

Install on the rear axle only and verify vehicle-specific fitment before service. Clean the rotor and braking surfaces before installation, and follow proper pad bedding procedures after replacement. For best results, inspect pads, caliper hardware, and brake fluid condition at the same time.

Quality Assurance

Each rotor is inspected after machining to confirm balance and critical dimensions, then checked again to ensure it meets OE specifications. DFC backs this rotor set with a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
