Detailed Product Description
The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed specifically for Ford Mustang models, providing a precise fit and enhanced braking capabilities. The rotors measure 330 mm in outside diameter with a nominal thickness of 28 mm, ensuring durability and compatibility with factory brake components. Featuring a vented rotor design with curved vanes, these rotors promote effective heat dissipation during aggressive driving or track use, reducing the risk of brake fade.
The cross-drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water from the braking surface, maintaining consistent stopping power. The coated hat finish offers corrosion resistance, extending the rotor's service life. Additionally, the floating disc mounting system allows for slight rotor movement, which helps prevent warping and uneven wear.
