The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors designed to improve braking efficiency and durability. This product line features rotors with both cross-drilled holes and slots, which help to evacuate gases, dust, and water from the braking surface. The vented rotor design enhances cooling, making these rotors suitable for trucks like the Ford F-150 and F-150 Heritage that may experience demanding driving conditions.

Technical Specifications and Features

These rotors have a nominal thickness of 1.024 inches (26.000 mm) and a discard thickness of 0.965 inches (24.500 mm), ensuring a solid lifespan before replacement is necessary. The overall height measures 2.047 inches (52.000 mm), and the outside diameter is 12.126 inches (308.000 mm). The rotors feature a 5.315 inch (135.000 mm) mounting bolt hole circle diameter with five lug holes sized at 0.598 inches (15.200 mm). The center hole diameter is 3.543 inches (90.000 mm). The rotor weighs approximately 19.25 lbs (8.75 kgs), balancing durability and performance. The hat finish is coated to resist corrosion, and the vane style is straight to optimize airflow and cooling.

Applications and Problem Solving

• Improves braking performance for Ford F-150 and F-150 Heritage trucks
• Reduces brake fade during heavy towing or hauling
• Helps prevent rotor warping caused by excessive heat buildup
• Maintains consistent brake pad contact by cleaning pad surface with slots and drilled holes
• Extends rotor life by resisting corrosion with coated hat finish

Installation Notes and Tips

These rotors are designed for direct replacement on compatible Ford F-150 and F-150 Heritage models with a 5-lug wheel pattern. Ensure the rotor thickness is checked before installation to confirm it meets or exceeds the discard thickness specification. The floating disc mounting allows for thermal expansion, so proper alignment during installation is important. Bearings and ABS tone rings are not included and should be reused or replaced as needed.
