Impreza 2005 blob eye wheels

[JohnBowskil]

Hi all I've just joined your forum and actually one week into a Subaru having driven another make for 12 years so far I'm loving the car. I was wandering what size wheels can fit in a standard unmodified arch as the alloy wheel place I'm looking at say anything from 17 inch to 20 inch is fine unmodded. I ask you guys as that's a hell of a size difference 3 inch

Thanks everyone 👍
