Welcome! Did you paint the stock wheels gunmetal from the bronze look in the last pic? I like it. Do you know what exhaust is on your car as well? Any other mods that you got it with?
As for wheels...any standard quality wheel is something to yearn for. You'll probably see more Rotas on WRXs than anything else because they are affordable. And for the price, the quality isn't terrible. Is there better? Of course...Rotas have been known to crack and break at times, but that's few and far between.
The BBS of the WRX world would probably be Rays (Volks, Gram Lights), Work, and Enkei. Then again, many WRXs and STIs do have some great looking non-stock BBS wheels as well.
