Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are precision-engineered vented rotors with a slotted surface designed to optimize braking performance for Toyota 4Runner, FJ Cruiser, and Tacoma vehicles. The vented rotor design features straight vanes that facilitate efficient heat dissipation, reducing the risk of brake fade during extended or aggressive braking. The slotted surface helps to clear brake dust, gas, and water from the pad surface, maintaining consistent friction and improving overall brake response.

These rotors have a coated hat finish that provides corrosion resistance, extending the rotor's service life. The floating disc mounting system allows for slight rotor movement, which helps reduce stress and warping. With a 6-lug hole pattern and a mounting bolt hole circle diameter of 139.7 mm (5.5 inches), these rotors are designed to fit securely on compatible Toyota models. The overall height measures 67.5 mm (2.657 inches), and the center hole diameter is 108 mm (4.252 inches), ensuring proper fitment and alignment.
