An interesting tidbit from that site that backs up previous articles--that the JDM STi weighs about 3200 lbs (1450kg). I think it's highly unlikely that our STi will be lighter than this. I am expecting the US STi to be about equal to the Evo VIII: 3250 lbs. It's too bad that there won't be Spec C in the US, but honestly I think I'd rather diet for a few months than loose the air conditioner.
