Dynamite Friction 7004-03056 Disc Brake Rotor Set - Front and Rear

Drilled and Slotted Brake Rotor Set

The Dynamite Friction DFC Rotors-Drilled and Slotted-Silver set is built for drivers who want OE-style fitment with added braking performance. Part number 7004-03056 is engineered for front and rear applications on select Hyundai Sonata and Kia Optima models, including 2020 Kia Optima and 2015-2019 Hyundai Sonata coverage.

These DFC brake rotors use drilled holes and slots to improve pad bite, manage heat, and clear debris from the rotor surface. The silver GEOSPEC coating helps protect the rotor finish while supporting a clean, service-ready appearance.

Product Details

DFC Premium Performance Brake Rotors are machined to tight tolerances and finished to meet OE specifications for durability, reliability, and stability. The rotor castings are processed with a non-directional finish to promote smoother stops and quieter operation, while vented rotors are electronically mill-balanced and inspected before release. This part number 7004-03056 is a direct-fit rotor set for select Hyundai Sonata and Kia Optima brake service needs.

Compatible With 2015-2019 Hyundai Sonata, front and rear; 2016-2017 Kia Optima, front and rear; 2018-2019 Kia Optima, front and rear; 2020 Kia Optima, front and rear. For 2018-2019 Kia Optima applications, the fitment notes specify a 305mm front disc.

What It Helps Address

• Brake fade from excess rotor heat
• Uneven pad contact during brake service
• Brake dust and debris buildup on the rotor face
• Pad glazing that can reduce braking consistency
• Rotor surface corrosion and finish wear

Installation Notes

Verify rotor size and brake package before installation, especially on 2018-2019 Kia Optima models with the 305mm front disc note. Clean the rotor surfaces before service and follow proper pad bed-in procedures after installation. Confirm front and rear placement matches the vehicle’s brake configuration.

Quality Assurance

DFC inspects each rotor for balance and critical specifications after machining. The 7004-03056 rotor set is backed by a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
