Detailed Product Description

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors are specifically designed for Toyota 4Runner and Tacoma models, providing reliable braking performance with a focus on heat management and durability. The vented rotor construction features straight vanes that allow air to flow through the rotor, helping to dissipate heat generated during braking. The cross-drilled holes and precision-machined slots improve pad bite and help evacuate gases, dust, and water from the rotor surface, which can enhance braking consistency and reduce the risk of brake fade.

These rotors have a floating disc mounting design, which allows slight movement between the rotor and hub to reduce stress and minimize warping over time. The rotor’s dimensions include an outside diameter of 318.5 mm and a nominal thickness of 21.8 mm, with a discard thickness of 20 mm, ensuring compatibility with factory specifications for Toyota 4Runner and Tacoma brake systems. The 6-lug hole pattern with a 139.7 mm bolt circle diameter matches OEM fitment requirements.

Applications and Problem Solving

• Improves braking performance for Toyota 4Runner and Tacoma vehicles
• Reduces brake fade during heavy or repeated braking
