idk, project nissan doesnt make horrible stuff.... I have their RUCA's, it's been almost a year daily driving, plus a few track events and still holding strong. The threads havent started to rust yet either, compared to other chinese made suspension arms. Not trying to stand up for knockoff companies, just giving my 2cents.
edit: o yeah, and tein inner and outer setup is good, but I suggest if you go that route to get moog outers because I havent been a huge fan of the tein outers, mine demolished first event and they were almost new....
