This threads 3 years old idk if the OP is still around here. Looks authentic. The fitment looks great.

 

If I remember correctly it was authentic but had been sitting in storage for a while and had been deformed a little.

 

I'm still lurking around.

The kit is authentic and J8635621 is right it had been in storage by the previous owner but wasn't deformed at all.

So far I've had no issues with the kit itself just the body shops I had chosen.
The paintwork is shoddy in some areas with peeling of the clearcoat.

Also the back bumper has really survived hell! There was a big windstorm a couple of years back which caused a tree to fall on the rear of the car! It hit the trunk and both tail-lights and ripped off the bumper. Vertex makes very strong stuff, it wasn't even damaged at all





Then 2 weeks after I got it fixed my neighbor had an emergency in the middle of the night and when they backed out of their driveway they tore a hole in the side of the rear bumper It was easily fixed though and looks good as new.
