I would however question his reasoning for bracing. The chassis on new-age Imprezas is extremely rigid and only benefits from strut braces if the suspension set-up is very stiff. If he already has stiff springs and uprated ARB's then he may get some benefit, otherwise he's just wasting money.

If the other mods aren't in place consider the Prodrive (or Eibach, cheaper but nearly as good) springs, then add front and rear solid droplinks and a good geometry set-up. See how he likes it and if he still wants it stiffer then add Whiteline ARB's and consider the bracing last.

All IMHO of course. It's his money.
