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

The StopTech Select 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, reducing brake fade and improving pad bite. This product line is tailored for drivers seeking reliable, consistent braking performance on street-driven Toyota 4Runner and Tacoma vehicles without requiring full race-spec components.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation during braking events. The rotor’s overall diameter of 296.8 mm and nominal thickness of 21.7 mm ensure compatibility with factory calipers and brake pads on the specified Toyota models. The floating mounting design and straight vane style contribute to rotor durability and thermal management. The rotor does not include ABS tone rings or bearings, so these components must be retained from the original equipment or sourced separately.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to maintain consistent brake performance
• Helps prevent glazing and uneven pad wear with slotted and drilled surface
• Addresses vibration and noise issues caused by warped or worn rotors
• Restores braking efficiency on Toyota 4Runner and Tacoma vehicles with worn OEM rotors

Installation Notes and Tips

• Ensure compatibility with Toyota 4Runner and Tacoma models before installation
• Retain or replace ABS tone rings and bearings as needed, since these are not included
• Inspect brake pads and calipers for wear and replace if necessary to optimize performance
• Follow manufacturer torque specifications for mounting bolts and lug nuts
• Perform a proper bed-in procedure after installation to maximize rotor and pad life
