Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are designed to meet the braking demands of mid-size sedans such as the Buick Lucerne and Chevrolet Impala. Featuring a slotted surface, these rotors help maintain clean pad contact by channeling away dust, gas, and water, which can improve braking consistency under various driving conditions. The vented rotor design with straight vanes enhances airflow, reducing heat buildup during repeated braking events. The coated hat finish provides corrosion resistance, extending rotor life and maintaining appearance.

With a floating disc mounting system and a 5-lug bolt pattern on a 4.5-inch (114.3 mm) bolt circle diameter, these rotors are engineered for precise fitment and reliable performance. The rotor’s nominal thickness of 1.185 inches (30.1 mm) ensures durability, while the discard thickness of 1.126 inches (28.6 mm) indicates the minimum safe thickness for replacement. The overall diameter of 11.929 inches (303 mm) and height of 2.055 inches (52.2 mm) align with factory specifications for the compatible vehicles.
