Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to meet the demands of drivers requiring reliable braking under various conditions. The drilled and slotted surface improves water and debris evacuation, while the vented rotor design helps reduce heat buildup during braking. The zinc silver hat finish adds an extra layer of protection against rust, making it suitable for vehicles like the Hyundai Santa Fe and Kia Sorento that may encounter diverse driving environments.

Technical Specifications and Features

This rotor measures 320 mm in outside diameter and 49.26 mm in overall height, with a center hole diameter of 69 mm. The rotor’s 5-lug bolt pattern with 12.5 mm diameter holes and a 114.3 mm bolt circle diameter ensures precise fitment on compatible Hyundai and Kia models. The nominal thickness of 28 mm and discard thickness of 26 mm provide clear service limits for maintenance. The directional slotted and drilled surface enhances braking response and helps maintain pad contact by reducing gas buildup.

Applications and Problem Solving

• Replacement rotor for Hyundai Santa Fe, Santa Fe Sport, Santa Fe XL, and Kia Sorento models
