The BMW 4 Series Brake Rotors (2) – Front – Stoptech – AeroRotor Drilled – '15-'16 are expertly crafted to replace your vehicle’s original factory rotors while retaining the factory brake calipers. These rotors are designed to enhance cooling, braking, and handling performance without altering the diameter or thickness from the factory standards.

StopTech AeroRotor Replacement Kits (ARK) incorporate advanced features to maximize performance, permitting independent expansion of the rotor and hat without coning due to the elongated drive pin holes. These sophisticated components feature AeroRotor friction rings with a patented internal vane design, plus pre-assembled billet aluminum AeroHats with directional stand-offs intended to optimize cooling airflow. This patented vane design efficiently circulates up to 80% more air than standard factory rotors, ensuring superior cooling and reduced fade during intense driving conditions, such as on the track. Furthermore, the 2-piece AeroRotors are crafted from aircraft-grade aluminum hats, making them up to 8 pounds lighter than stock alternatives, thus allowing for quicker acceleration, deceleration, and enhanced vehicle handling.
