The cross-drilled and slotted surface pattern helps evacuate gases and debris, reducing brake fade and maintaining consistent friction. Vented rotor construction further aids in cooling, making this product line suitable for spirited driving and track use. The coated hat finish provides additional protection against rust, ensuring durability over time.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Fitment\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is specifically engineered for Pontiac GTO models, featuring a 285.7 mm (11.248 inch) outside diameter and a 79.5 mm (3.130 inch) overall height. The rotor is vented with pillar-style vanes to optimize airflow and heat dissipation during braking. It includes five lug holes sized at 12.7 mm (0.5 inch) diameter on a 120 mm (4.724 inch) bolt circle diameter, ensuring proper fitment. The rotor’s nominal thickness is 18.0 mm (0.709 inch), with a discard thickness of 16.0 mm (0.630 inch), indicating when replacement is necessary. The center hole diameter measures 70.1 mm (2.760 inch), and the rotor weighs approximately 6.91 kg (15.2 lbs). This part does not include ABS tone rings or bearings.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive or repeated braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eMaintains consistent brake pad contact by clearing debris and gases\u003c\/li\u003e\n\u003cli\u003eResists corrosion with coated hat finish for longer service life\u003c\/li\u003e\n\u003cli\u003eCompatible replacement for worn or damaged Pontiac GTO rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness before installation\u003c\/li\u003e\n\u003cli\u003eClean mounting surfaces to prevent uneven rotor seating\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for lug nuts to avoid rotor damage\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with existing brake pads and calipers on Pontiac GTO\u003c\/li\u003e\n\u003cli\u003eInspect related components such as wheel bearings and hub assembly during installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors are manufactured to meet or exceed OEM specifications for fit, form, and function.
