The PowerStop Evolution drilled and slotted rotor pair for 2016–2018 Volvo S90 is a bolt-on upgrade that improves cooling and rotor surface cleanliness. Precision cross-drilled holes and rounded slots remove gases, dust and moisture to preserve a clean friction contact patch, while zinc plating resists corrosion. Manufactured to strict tolerances for runout and dynamically balanced, the pair installs without modifications.
