Note 1: Preserve the already accepted375 mm/source5 project-owner complete-wheel visual bridge, original Scion iM donor root and exact owner decision. The owner matched the2016 Scion iA wheel to the2016 Scion iM donor; this target is the documented same DL four-door sedan under the Toyota Yaris iA name in MY2017–2018, not the ordinary same-year Yaris hatchback or Corolla. Toyota manufacturer name-change and IIHS exact body evidence retain the full physical2016–2018 scope, with Scion badge2016 and Toyota Yaris iA badge2017–2018. The target, current raw record, accepted source and catalog relationship are already integrated; the old current assessment intake-pending copies are obsolete. This is inherited owner evidence, not a new target physical measurement, confidence upgrade, independent source or confirmed-round geometry. Return to measurement
