The rotor’s overall height measures 67.5 mm (2.657 inches), with an outside diameter of 310 mm (12.205 inches). Designed with a 5-stud lug hole pattern spaced on a 114.3 mm (4.5 inch) bolt circle diameter, it fits specific Lexus GS and IS models precisely. The rotor includes a floating disc mounting system to accommodate thermal expansion and reduce stress, while the vented design with straight vanes promotes consistent cooling during heavy braking. The hat section is coated to protect against rust and corrosion, maintaining rotor integrity over time. This rotor does not include ABS tone rings or bearings.\u003c\/p\u003e\u003ch2\u003eStopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors Product Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors line is designed to enhance braking performance by combining cross-drilled holes and precision slots.
