Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors that combine cross-drilled holes and slots to optimize braking efficiency. This design helps to evacuate gases, dust, and water from the rotor surface, improving pad bite and reducing the risk of brake fade under demanding conditions. The vented rotor construction with straight vanes further enhances cooling, making these rotors suitable for heavy-duty use on trucks and SUVs such as the Cadillac Escalade EXT and Chevrolet Avalanche.

Technical Specifications and Features

These rotors feature a nominal thickness of 0.787 inches (20.000 mm) and a discard thickness of 0.728 inches (18.500 mm), ensuring durability and longevity. The overall height measures 3.362 inches (85.400 mm), with an outside diameter of 13.583 inches (345.000 mm). The rotor includes six stud/lug holes with a diameter of 0.650 inches (16.500 mm) and a mounting bolt hole circle diameter of 5.500 inches (139.700 mm). The center hole diameter is 3.091 inches (78.500 mm), designed for precise fitment. The rotor weighs approximately 9.77 kg, balancing strength and heat dissipation. Note that this rotor does not include an ABS tone ring or bearings.

Applications and Problem Solving

• Reduces brake fade during heavy towing or hauling in vehicles like the GMC Sierra 1500 Limited
• Improves braking response and pad bite in wet or dusty conditions for the Chevrolet Suburban 1500
• Helps maintain consistent braking performance under high heat from frequent stop-and-go driving in the Cadillac Escalade ESV
• Minimizes rotor warping and vibration for smoother stops in the GMC Yukon
• Extends rotor life by resisting corrosion with a coated hat finish on the Chevrolet Silverado 1500 LD

Installation Notes and Tips

• Ensure compatibility with your vehicle’s 6-lug wheel configuration before installation
• Inspect brake pads and calipers for wear and replace if necessary to maximize rotor performance
• Follow manufacturer torque specifications for mounting bolts to avoid rotor damage
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Check for proper rotor thickness and discard limits during routine maintenance
