Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed specifically for the Pontiac G8, providing a precise fit and enhanced braking capabilities. The rotors measure 321.1 mm in outside diameter and have a nominal thickness of 30.0 mm, ensuring durability and longevity. Featuring a vented rotor construction with curved vanes, these rotors improve heat dissipation during heavy braking, reducing the risk of brake fade. The cross-drilled and slotted surface pattern helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and performance. The coated hat finish protects against corrosion, extending the rotor's service life. Additionally, the floating disc mounting design allows for slight movement to reduce stress and improve rotor alignment during operation.
