Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are specifically designed for Toyota 4Runner and Tacoma models, providing reliable braking performance in both daily driving and more demanding conditions. The rotors feature a vented design with straight vanes that promote efficient heat dissipation, reducing the risk of brake fade during extended use. The cross-drilled and slotted surface pattern helps to evacuate gases, dust, and water from the braking surface, improving pad contact and overall stopping power.

These rotors have a coated hat finish that protects against rust and corrosion, extending the service life of the rotor. The floating disc mounting system allows for slight movement between the rotor and hub, which helps maintain proper alignment and reduces stress on the braking components. With an overall height of 70.5 mm (2.776 inches) and a center hole diameter of 108.1 mm (4.256 inches), these rotors are engineered to meet precise fitment requirements for the specified Toyota models.
