Detailed Product Description

This disc brake rotor from Dynamite Friction is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering reliable braking performance with enhanced thermal management. The rotor’s vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface helps evacuate gases, dust, and water, improving pad contact and braking consistency. The rotor’s plain disc finish combined with a rust resistant coating and Geospec silver grey hat finish provides durability and corrosion resistance, extending the rotor’s service life.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during aggressive driving or towing
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner braking components
• Maintains consistent braking performance on Genesis G70 and Kia Stinger models
• Prevents premature rotor wear with rust resistant coating and durable finishes

Installation Notes and Tips

Ensure the rotor is installed on compatible Genesis G70 or Kia Stinger models matching the specified bolt pattern and dimensions. Verify the rotor thickness before installation; replace if below the discard thickness of 26 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.

Quality Assurance

Dynamite Friction’s DFC Geoperformance Rotor line is manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and precision machining contribute to long-lasting performance. Warranty information is available through the manufacturer or authorized distributors.
