Im leaning towards doing my STi swap with my tax refund this year.

Heres my dilemma, I want to keep my 5x100 bolt pattern since I already have 3 sets of wheels and tires (I have two Subarus) so since Im assuming I have to swap shafts I need to seek out an 04 STi right? Any other years work (I think no)?

Also, will I have to swap knuckles?

And lastly, what about my brakes? Do I HAVE to swap rotors and whatnot? the reason I am asking is that I am at the point now where I need brake pads for my outback and dont want to upgrade my rotors and pads only to be forced into STi brakes whenever I get around to actually doing the swap.

Feel free to pick my post apart, but please let me know what you think!
