The PowerStop Evolution Drilled & Slotted Rotor pair for 2010–2011 Audi S4 rear applications is a bolt-on upgrade that improves cooling and pad contact under demanding conditions. Precision cross-drilled holes and rounded slots clear gases, dust and moisture while minimizing stress cracking. Zinc dichromate plating helps resist corrosion and rotors are machined to strict DTV/runout tolerances and dynamically balanced for smooth performance.
