I didn't bother trimming, they said they can thin out the spray at the edges, I will cross that road when the time comes, and I don't plan on worrying too muc about the body clips, so I have some wiggle room.
As for the door cladding, not a whole lot of area to fit an emblem, nothing flat enough. I ended up scrapping that idea and went with the factory 3.5l spot and placed old school ISUZU emblems there.
