Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to provide consistent braking performance under demanding conditions. The cross-drilled and slotted surface helps to evacuate heat, brake dust, and gases generated during braking, reducing the risk of brake fade. The vented rotor with straight vanes improves airflow, allowing the rotor to cool more efficiently during operation. The coated hat finish protects against rust and corrosion, maintaining the rotor’s structural integrity over time. This rotor uses a floating disc mounting system, which helps to accommodate thermal expansion and reduce stress on the rotor, contributing to longer service life.

With an outside diameter of 12.803 inches (325.2 mm) and a nominal thickness of 1.142 inches (29.0 mm), this rotor meets the specifications required for Chevrolet Trailblazer and Saab 9-7x models. The mounting bolt hole circle diameter of 127 mm (5.0 inches) and six lug holes with a diameter of 0.524 inches (13.3 mm) ensure proper fitment and secure installation.
