Welcome to NICO Club!
My first search showed this company is a manufacturer from Malaysia. Then that page stopped working and I looked at the next result saying they are from USA. Then I find some swedish people giving reviews on some braces and saying they company is from Australia.
In photo 2 of 2 I see the OEM brace has rectangles on the outermost ends that don't appear in photo 1 of 1. Photo 1 of 1 might be really crumby quality but looks like a photoshop of new parts superimposed on the bottom of a car. There's no detailed information of materials used or images of the weld quality. Is there a warranty and how will it get replaced if it breaks under stress? It sounds like it's difficult to purchase. I don't know if any of that matters.
I would get OEM, use some nice new stiff bushings, rust proof it as much as possible and plan for regular undercarriage rinsing during the winter months assuming your roads get salted.
If you get this part, please let us know how it goes. Ease of purchase, build quality, fitment, maybe a weight comparison. Then after a year or two, how well it holds up. I'm sure others would be interested in that information. Good luck!
