Alright, I am the guinea pig for the group but I did it.
I installed the Arctic fender flares from Fjallasport.
Cost-plus shipping to the USA was around $1600. Granted, these are hand-crafted in Iceland and are really high quality.
These were not an exact fit on my pathfinder because mine has the facelift in the front being it's an 08 and up model.
That being said, they mounted up without any issues using threaded rivnuts and silicone caulking for water adhesion protection.
I have a titan swap plus 1.5-inch wheel spacers upfront so that goes to show how much width I am at upfront. The rear wheels have just 1.50-inch spacers.
Happy to answer any questions you have for me!
