Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are specifically designed for the Chevrolet Astro and GMC Safari, providing reliable braking performance with a focus on heat management and durability. The vented rotor design incorporates straight vanes that facilitate airflow, helping to dissipate heat generated during braking. This reduces the risk of brake fade during extended use. The slotted surface improves pad bite and helps channel away dust, gas, and water, maintaining consistent braking performance in various driving conditions.

The rotor features a coated hat finish that protects against corrosion, extending the rotor's service life. The floating disc mounting system allows for slight movement between the rotor and hub, which can improve rotor alignment and reduce the risk of warping. With a 5-lug bolt pattern and a 5.000 inch bolt circle diameter, these rotors are designed to fit securely on the specified vehicle models.
