The pillar-style vane design promotes airflow between the rotor faces, further reducing operating temperatures. The rotor’s hat is coated to resist corrosion, extending service life and maintaining appearance. These rotors have a floating disc mounting system that accommodates thermal expansion, reducing the risk of warping. With a nominal thickness of 29.8 mm and an outside diameter of 320 mm, these rotors are designed to meet the exact specifications required for Audi A4, A4 Quattro, A5, A5 Quattro, and Q5 models. The 5-lug hole pattern with a 112 mm bolt circle diameter ensures proper fitment and secure installation.\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 for drivers seeking enhanced braking performance with reliable heat management.
