Power Stop Evolution drilled & slotted zinc-plated rotors (pair) for 2013–2018 BMW 320i xDrive are a bolt-on upgrade to improve cooling and performance. Precision cross-drilled holes and rounded slots sweep away gases, dust, and moisture for cleaner friction contact and better heat dissipation during demanding conditions. Manufactured to tight tolerances for DTV and runout, zinc plating resists corrosion, chamfered holes reduce stress cracking, and rotors are dynamically balanced and sold as a pair for matched performance.
