The Erebuni kit (like all Erebuni kits) is a copy.
They copied the Nissan factory option kit from Japan.
Fitment will be an issue as 99% of Erebuni kits are not symmetrical...
If you could, I would try to get the Nissan kit.
"PrimeraGT" aka Henry has the front bumper fitted and at the Nopi Nationals (for you UK guys, thats a huge show here yearly) Erebuni approached him and said "you didnt put an Erebuni sticker on your car to support us?"
I believe Henry replied with something along the lines of "Hell no, there was so much cutting and patching involved in fitting it that its a custom bumper, not an Erebuni bumper!!"
