StopTech Sport Cross-Drilled Disc Brake Rotors Product Line

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors that provide improved cooling and consistent braking. The cross-drilled design helps reduce heat buildup and brake fade, while the vented rotor construction promotes airflow. This product line is suitable for drivers who require enhanced braking reliability without modifying their vehicle’s original brake system. The coated hat finish adds protection against corrosion, extending rotor life in various driving environments.

Technical Details and Specifications

This disc brake rotor features a vented design with straight vanes to optimize heat dissipation during braking. The cross-drilled surface improves water and gas evacuation from the rotor face, maintaining consistent pad contact. The rotor’s overall height measures 3.157 inches (80.2 mm), and it includes six lug holes arranged on a 5.315 inch (135 mm) bolt circle diameter. The center hole diameter is 3.547 inches (90.1 mm), ensuring proper fitment on the Ford F-150 hub assembly. Note that this rotor does not include ABS tone rings or bearings.

Applications and Problem Solving

• Replaces worn or warped rotors on Ford F-150 models
• Reduces brake fade during heavy towing or hauling
• Improves heat dissipation for consistent braking performance
• Addresses rotor corrosion with coated hat finish
• Enhances braking response in wet or humid conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.906 inches (23.0 mm) before installation. Clean the rotor surface to remove any protective coatings or oils prior to mounting. Verify the 6-lug bolt pattern and center hole diameter match the vehicle hub. Use proper torque specifications for lug nuts to avoid rotor warping. This rotor is designed for floating/dih disc mounting systems common on Ford F-150 trucks.
