The PowerStop Evolution drilled and slotted front rotors for 2012–2015 Scion iQ are a bolt-on upgrade that improves cooling and wet performance. Precision cross-drilled holes and rounded slots sweep away gases, dust and moisture to maintain a clean friction surface, while zinc plating resists corrosion and strict mill-balance tolerances reduce DTV and runout for smooth, quiet operation.
