The PowerStop Evolution drilled and slotted rotor pair for 2003–2005 BMW Z4 rear applications brings improved cooling and consistent contact by using precision cross-drilled holes and rounded slots that sweep away gasses, dust and water. Zinc dichromate plating helps prevent rust, and OE-matched weight, vane count and tolerances mean these rotors install as a direct bolt-on replacement.
