These rotors feature a vented design with straight vanes that promote efficient airflow, helping to reduce heat buildup during braking. The cross-drilled surface improves water and gas evacuation, which enhances braking consistency in wet or high-performance driving conditions. The rotor hat is coated to protect against corrosion, ensuring durability over time. With a floating disc mounting system, the rotor can better accommodate thermal expansion and reduce stress on the braking components. The rotor measures 312 mm in outside diameter and 73.6 mm in overall height, with a 5-lug bolt pattern on a 120 mm circle, making it a precise replacement for compatible BMW models.\u003c\/p\u003e\u003ch2\u003eAbout StopTech Sport Cross-Drilled Disc Brake Rotors\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to offer enhanced braking performance for sport and daily driving applications.
