The rotor’s surface is both slotted and cross-drilled, which helps to evacuate gases, dust, and water from the braking surface, improving pad bite and overall braking consistency. The coated hat finish provides corrosion resistance, maintaining the rotor’s integrity over time. With an overall height of 67.2 mm and a center hole diameter of 75 mm, this rotor is engineered for precise fitment on compatible BMW vehicles. The rotor weighs approximately 8.27 kg (18.2 lbs), balancing durability and performance.\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 offer enhanced braking performance for street and light track use. This product line focuses on improving heat dissipation and brake pad cleaning through its cross-drilled and slotted rotor surface.
