RHD is legit.
Regardless of which place you go with, it's going to be probably a 6+ month wait for production, then surface shipping, then freight to you or your body shop.
I believe there are some shenanigans going on about North American distribution of Varis; certain outlets were trying to get exclusive distribution rights and effectively "block off" everyone else from getting stuff directly from Varis. Not sure who won that fight, but best I can find is:

That means Vivid or Evasive is ordering through BP
You should ask RHD what their shipping arrangements will be. Going with a Japanese company raises the additional hurdle that if you have any issues such as a damaged hood in transit, you're going through a Japanese company, instead of a place you can just call.
