• Vented disc type with drilled and slotted surface for improved cooling
• Directional brake surface optimized for performance and wear
• Rust resistant coating to extend rotor life
• Geospec silver grey hat finish for corrosion resistance and durability
• Fits vehicles with 5 lug holes and 114.3 mm bolt circle diameter
• Outside diameter of 305 mm and overall height of 48.7 mm

Detailed Product Description

This disc brake rotor is specifically designed for Hyundai and Kia models including the Elantra, K5, Kona, Kona Electric, Niro EV, and Sonata. The rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade under demanding conditions. The drilled and slotted surface improves water and debris evacuation, maintaining consistent brake pad contact and performance. The directional surface pattern is engineered to optimize braking efficiency and rotor longevity.

The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, ensuring it meets safety and performance standards. The rotor’s hat is finished in Geospec silver grey, providing additional corrosion resistance, complemented by a rust resistant coating on the disc surface. The 5 bolt holes with a 12.5 mm diameter and a bolt circle diameter of 114.3 mm ensure proper fitment and secure mounting.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line focuses on delivering rotors with enhanced heat management and surface design to improve braking performance. This line combines vented rotor construction with drilled and slotted surfaces to reduce heat buildup and maintain consistent braking under various driving conditions. The directional surface pattern further supports efficient brake pad contact and wear distribution, making it suitable for daily driving and moderate performance applications.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or debris-prone environments
• Minimizes rotor warping and uneven pad wear
• Prevents rust and corrosion on braking surfaces
• Ensures proper fitment for Hyundai Elantra, Kia K5, and other compatible models

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 23 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the vehicle’s hub using the 5 lug holes and 114.3 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted (830-03066R) is manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and Geospec silver grey hat finish contribute to long-term durability. While no specific warranty information is provided, this rotor is designed for reliable performance on compatible Hyundai and Kia vehicles.
