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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking efficiency by combining cross-drilled holes and precision slots. This design improves pad bite and helps evacuate gases, dust, and water from the rotor surface. The vented construction further aids in heat dissipation, making these rotors suitable for vehicles like the Hummer H1 that require consistent braking performance under demanding conditions.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling. The rotor's overall height measures 1.362 inches (34.6 mm), and it mounts behind the hub for secure installation. The center hole diameter is 3.547 inches (90.1 mm), ensuring proper alignment on the Hummer H1. The rotor does not include an ABS tone ring or bearings, so these components must be sourced separately if required.

Applications and Problem Solving

• Reduces brake fade during extended or heavy braking
• Improves braking response and pad bite in wet or dusty conditions
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes corrosion with coated hat finish for longer service life
• Compatible with Hummer H1 models requiring 6-bolt vented rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.815 inches) before installation
• Verify mounting bolt hole pattern (6 holes, 4.331 inch bolt circle) matches vehicle hub
• Clean rotor surface before installation to remove any protective coatings
• Use proper torque specifications for mounting bolts to avoid rotor damage
• Check compatibility with existing brake pads and hardware
