Dynamite Friction 7002-21048 Disc Brake Rotor Set - Rear

Rear Drilled and Slotted Rotor Set for Sonata and K5

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver, part number 7002-21048, is a rear disc brake rotor set built for drivers who want OE-style fitment with added performance features. It is compatible with 2021-2026 Hyundai Sonata N-Line rear applications and 2021-2026 Kia K5 rear applications.

Key Features

• Drilled and slotted rotor design for improved pad bite and more consistent braking response
• Slots help clear brake dust and road debris while reducing pad glazing
• Drilled holes reduce heat buildup during repeated stops
• GEOSPEC coated cast iron construction for durability and corrosion resistance
• Machined to tight tolerances with a non-directional finish for smoother pad bed-in
• 100% inspected for balance and critical dimensions before release

Product Line Details

The DFC Rotors-Drilled and Slotted-Silver line combines performance-oriented rotor geometry with OE-matching engineering. For rear brake service on a Hyundai Sonata or Kia K5, this line is built to deliver stable braking feel, even wear, and a clean finish that supports quieter operation after proper pad bedding.

Detailed Description

Part number 7002-21048 is a rear disc brake rotor set made from G3000/G11H18 cast iron and processed to OE specifications for fit, durability, and stability. The drilled and slotted surface is designed to increase pad contact bite, manage heat, and keep the braking surface cleaner under wet or debris-heavy conditions. Each rotor receives a non-directional finish to promote even pad transfer and smoother stops, then undergoes balance correction and final inspection for critical dimensions.

Fits 2021-2026 Hyundai Sonata, rear, N-Line. Fits 2021-2026 Kia K5, rear.

Common Brake Issues It Can Address

• Brake fade from heat buildup during repeated stops
• Uneven pad contact or glazing on worn rear rotors
• Reduced braking response in wet conditions
• Rotor vibration caused by balance or surface inconsistency
• Noise and roughness from contaminated braking surfaces

Installation Notes and Tips

Confirm rear axle fitment before ordering, especially on the 2021-2026 Hyundai Sonata N-Line. Clean the hub face thoroughly, inspect pads and hardware condition, and follow the pad manufacturer’s bedding procedure after installation. For best results, replace rotors in axle pairs and verify rotor thickness and runout during service.

Quality Assurance

DFC machines each rotor to tight tolerances, applies a non-directional finish, and performs 100% inspection for balance and critical attributes. Part number 7002-21048 is backed by a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
