These rotors feature a vented design with straight vanes that promote efficient heat dissipation during braking, reducing the risk of brake fade. The slotted surface improves pad bite and helps evacuate gases and debris from the rotor surface, maintaining consistent braking performance. The coated hat finish protects against rust and corrosion, which is critical for vehicles exposed to harsh environments.\u003c\/p\u003e\u003cp\u003eWith a floating disc mounting system, these rotors accommodate thermal expansion and contraction, reducing the risk of warping under heavy use. The rotor’s dimensions, including an outside diameter of 355 mm and a nominal thickness of 40 mm, ensure compatibility with the specified Chevrolet and GMC models. The 8-lug hole pattern and mounting bolt circle diameter of 180 mm provide a secure fit for the heavy-duty applications these trucks demand.\u003c\/p\u003e\u003ch2\u003eStopTech Sport Slotted Disc Brake Rotors Product Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Slotted Disc Brake Rotors line is designed to meet the needs of performance and heavy-duty vehicles requiring enhanced braking capabilities.
