i have no idea why tirerack does this or that, maybe something is up with how the data was entered into their computer. Maybe they figure they are too expensive yet they do offer the oz which are priced higher. As long as the imp has the same hub diameter and etc I would assume you are fine, perhaps they might rub a little dunno too many variables for me to figure out what goes through a corporations head. When I input the sti i do not see the bbs, when i input the wrx i see bbs. I would say contact luke @ tirerack and ask him why.
