tire warehouse and a few local shops are complete idiots. Again, 15" wheels will clear your brakes let alone 16". FFS, I am not lieing or making shit up. Go look up pictures of your car with 16" wheels, they're everywhere. Your car has stock 17" wheels so your local morons don't want to have to THINK for a living and are sure that 17" will clear. That's all it means. You should look up the 02-05 WRX, used almost identical brakes to the ones on your car and came stock with 16" wheels. In fact, the stock wheels from an 02-05 WRX will fit on your car just fine. The 06-07 WRX had larger brakes than your car and they STILL fit several different 16" designs. Not to be technical, but you can even fit some custom 16x8.5" brakes over STi BREMBOS! The idea that your stock brakes are too big for 16" wheels is absurd.
