if the stock wheels are a semi-forged - perhaps the semi-solid forging method which SSF uses for their wheels, tho you'd think STi would play that up if they were - that's a good thing. if you're not racing, spending the extra money for the weight advantage of forged wheels seems silly. in theory the added strength is a good thing, but I've found that if you pay attention to the roads you drive on normally, you can learn the locations of most of the nasty potholes - it got me thru 45k on 40 & 45 series 17" tires w/o any wheel or tire damage - you can survive.
my bet is we get the "normal" split 5-spoke wheels in a choice of colors (gold or silver of some sort) like the previous rumours & have the 18" Spec-C wheels as a dealer option.
I think I'd opt for aftermarket before I'd pay dealer prices for Subaru wheels, but since I'm not going to track the car heavily (I have a dedicated car for that) I'll likely just swap on 17" snows onto the stock wheels in the winter.
still torn on colors...
