PowerStop Evolution drilled and slotted rotors (zinc plated) are a rear rotor pair for 2003–2008 BMW Z4 that improve brake cooling and keep the rotor surface clear of debris. Precision cross-drilling and rounded slots sweep away gasses, dust and moisture for a cleaner contact patch, chamfered holes reduce stress cracking, and zinc plating protects against corrosion. These rotors are dynamically balanced and match OE vane and weight.
