DFC Geoperformance Rotor - Drilled and Slotted Product Line
The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction is designed to provide reliable braking performance with enhanced thermal management. The combination of drilled holes and directional slots helps reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes airflow to keep temperatures down. This product line is suitable for drivers seeking improved brake response and durability on performance-oriented vehicles like the Genesis G70 and Kia Stinger.
Technical Details and Specifications
This disc brake rotor is constructed with a nominal thickness of 30 mm and a discard thickness of 28 mm, ensuring a solid lifespan before replacement is necessary. The rotor’s 345 mm outside diameter and 57 mm height are matched precisely to the fitment requirements of the Genesis G70 and Kia Stinger. The rotor features a plain disc finish with a Geospec silver grey hat finish that includes a rust resistant coating to protect against corrosion. The 5 bolt holes, each 12.5 mm in diameter, are arranged on a 114.3 mm bolt circle diameter, with a center hole diameter of 69 mm, ensuring proper fitment and secure mounting.
Applications and Problem Solving
- Improves brake cooling to reduce fade during aggressive driving or towing
- Helps maintain consistent braking performance in wet or dusty conditions
