The Power Stop Evolution drilled and slotted rotor pair for 2004–2005 Buick Rainier front applications is a direct-fit upgrade that enhances brake cooling and contact consistency for smoother stopping. Cross-drilled holes increase airflow while rounded slots clear gases, dust, and water; chamfered holes help prevent stress cracking. Silver zinc dichromate plating guards against corrosion, and rotors are dynamically mill-balanced and produced to strict DTV and runout tolerances. Sold as a pair and installs without modification.
