Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed specifically for the Pontiac GTO, providing a precise fit and enhanced braking capability. The vented rotor design incorporates pillar-style vanes that improve airflow and heat dissipation, reducing the risk of brake fade during demanding driving conditions. The cross-drilled and slotted surface pattern helps to evacuate gases, dust, and water from the rotor surface, maintaining consistent pad contact and improving overall braking response.

The rotor features a coated hat finish that protects against corrosion and extends the rotor's service life. With a floating disc mounting system, this rotor allows for slight movement to reduce stress and improve thermal expansion management. The rotor measures 12.579 inches in outside diameter and has a nominal thickness of 1.260 inches, with a discard thickness of 1.181 inches, ensuring it meets OEM specifications for safe operation.
