The rotor measures 340 mm in outside diameter and 43.100 mm in overall height, with a 5-lug bolt pattern (108 mm bolt circle diameter) and a center hole diameter of 63.5 mm. The rotor’s surface is cross-drilled and slotted, which helps to reduce brake fade by improving heat dissipation and removing brake dust and gases during braking. The coated hat finish protects against rust and corrosion, maintaining rotor integrity over time. The floating disc mounting design allows for slight movement between the rotor and hat, reducing stress and improving thermal expansion handling.\u003c\/p\u003e\u003ch2\u003eAbout StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for street and light track use.
