• Center hole diameter: 69 mm

Detailed Product Description

This disc brake rotor is specifically designed for the Hyundai Genesis Coupe, providing a precise fit and reliable braking performance. The rotor’s vented construction allows air to flow between the rotor faces, reducing heat buildup during braking and minimizing the risk of brake fade. The directional slotted and drilled surface improves water and gas evacuation from the braking surface, which helps maintain consistent friction and reduces brake pad glazing.

The rotor’s nominal thickness of 20 mm ensures structural integrity, while the discard thickness of 18 mm indicates when replacement is necessary to maintain safety and performance. The rust resistant coating and Geospec silver grey hat finish protect against corrosion, extending the rotor’s service life in various driving conditions.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors with enhanced thermal management and surface design. This product line incorporates drilled holes and slots arranged directionally to optimize brake pad contact and heat dissipation. These features are intended to improve braking consistency and rotor longevity, particularly for performance-oriented vehicles like the Hyundai Genesis Coupe.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves wet weather braking performance by channeling water away
• Minimizes brake pad glazing and uneven wear
• Helps prevent rotor warping caused by excessive heat
• Extends rotor lifespan through corrosion resistance

Installation Notes and Tips

Ensure the rotor is compatible with the Hyundai Genesis Coupe model year before installation. Verify that the bolt hole pattern (5 holes, 12.5 mm diameter) and bolt circle diameter (114.3 mm) match the vehicle specifications. Clean the rotor surface of any protective coatings before mounting to avoid brake pad contamination. Proper torque specifications should be followed when securing the rotor to the hub to prevent warping.

Quality Assurance

Dynamite Friction manufactures the 830-03031L rotor to meet industry standards for durability and performance. The rust resistant coating and precision machining contribute to consistent braking and extended rotor life. Warranty information is available through the manufacturer and should be consulted for specific coverage details.
