PowerStop Evolution drilled and slotted rotors (zinc plated) are a rear rotor pair for 2014–2016 BMW 228i that upgrade cooling and keep the friction surface clean. Precision cross-drilled holes and rounded slots clear gasses, dust and moisture while chamfered drill holes minimize stress cracking. Zinc plating protects against corrosion and dynamic mill balancing with OE-matched weight and vane count ensures smooth, bolt-on performance.
