About StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide improved braking performance through enhanced rotor surface technology. The combination of cross-drilled holes and precision slots helps to evacuate gases, dust, and water from the braking surface, which can improve pad bite and reduce brake fade during demanding driving conditions. The vented rotor design further aids in heat dissipation, making these rotors suitable for both daily driving and spirited use on compatible Hyundai and Kia vehicles.

Detailed Product Description

This disc brake rotor features a vented design with straight vanes that promote efficient airflow to keep rotor temperatures in check. The rotor’s surface is cross-drilled and slotted, which helps maintain consistent braking performance by reducing heat buildup and clearing debris from the pad contact area. The coated hat finish provides corrosion resistance, extending the rotor’s service life. With a floating disc mounting system and two additional miscellaneous holes, this rotor is engineered for precise fitment and durability. It weighs approximately 15.75 lbs (7.16 kg), balancing strength and weight for optimal performance.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup during aggressive driving
• Improves braking response in wet or dusty conditions by clearing water and debris
• Minimizes rotor warping through vented design and floating mounting
• Enhances overall brake system longevity with corrosion-resistant coating
• Provides consistent pad contact for smoother braking performance

Installation Notes and Tips

• Ensure compatibility with your specific Hyundai or Kia model, such as Elantra, Sonata, or Sportage
• Check rotor thickness before installation; replace if below discard thickness of 0.961 inches (24.4 mm)
• Use proper torque specifications for the 5 lug nuts on the 4.5 inch (114.3 mm) bolt circle
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Professional installation is recommended to ensure correct rotor alignment and mounting
