WHAT?!?!?! Those are TINY! This is ATLANTA, BEEOTCH! Where da' playahs play! If they ain't twanky deuces, I'm walkin! I'm kidding, of course. OP, I'd try and find some 17 inch BBSs from an 04, but they carry a price tag. Those are definitely lighter than the WRX wheels, though.
Short answer is yes but only by a pound but 5x114.3 bolt pattern for the STI 04 STI BBS 17x7.5 and weighs in just under 16lbs 02-05 WRX 16x6.5 15.6lbs
Well, it appears my erroneous info is erroneous. I recalled researching it and was thinking about the 17 inch wheels on the 06+ WRX being heavier. My bad. B Reel is obviously spot on.
