I just bought a 2004 Forester with 16" aluminum wheels and it is in need of a little work. First thing on the list is new brakes. Rather than just replacing the factory rotors and a new set of pads are there any simple upgrades that can be done, front and rear. I have read that 06-07 WRX rotors and calipers might bolt right on. However I have not read a definite answer to this. Has anyone here done a similar upgrade? I am looking for simple bolt on, no modifications and I don't want to brake the bank. Thanks
