Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor features a vented design with pillar-style vanes that promote airflow to maintain optimal operating temperatures. The cross-drilled and slotted surface pattern helps to evacuate brake dust, gases, and water, improving pad bite and reducing the risk of brake fade during aggressive driving or track use. The rotor’s coated hat finish provides corrosion resistance, which is essential for maintaining performance and appearance over time.

With a nominal thickness of 28.0 mm (1.102 inches) and a discard thickness of 26.0 mm (1.024 inches), this rotor meets strict specifications for durability and safety. The overall height measures 47.6 mm (1.874 inches), ensuring proper clearance and compatibility with the braking system of the Cadillac CTS and Chevrolet Camaro models. The rotor is designed for vehicles with 5 lug holes, each 16.5 mm (0.650 inches) in diameter, arranged on a 120 mm (4.724 inches) bolt circle diameter.
