Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (127.66073L) are designed to meet the braking demands of Chevrolet Equinox and GMC Terrain drivers who require reliable stopping power. The rotors feature a vented design with straight vanes that promote airflow, reducing heat buildup during braking. The cross-drilled and slotted surface helps to evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade. The coated hat finish provides corrosion resistance, helping maintain rotor integrity over time. With a nominal thickness of 0.787 inches and a discard thickness of 0.724 inches, these rotors offer a balance of durability and performance. The rotor’s 11.929-inch diameter and 2.823-inch overall height ensure proper fitment and compatibility with the specified vehicles.
