PowerStop Evolution drilled and slotted rotors (zinc plated) are a direct-fit rear rotor pair for 2009–2016 BMW Z4, designed to improve cooling and maintain a clean friction surface. Precision cross-drilled holes and rounded slots evacuate gasses, dust and water; chamfered holes reduce stress cracking. Zinc plating resists corrosion and 100% dynamic mill balancing with OE-matched vane and weight promotes smooth, quiet braking.
