PowerStop Evolution drilled-and-slotted zinc-plated rotors provide a bolt-on front rotor upgrade for 2007–2010 Chevrolet Cobalt applications. Precision cross-drilled holes and rounded slots improve cooling and help clear gasses, dust, and moisture for a cleaner friction surface. Rotors are manufactured to strict DTV and runout tolerances, zinc plated for corrosion resistance, dynamically mill-balanced and sold as a pair.
