^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^The regular wrx calipers are the same as yours, and the rotors are only 1/8"(ish) larger in diameter. Buy a Front & Rear set of Porterfield R4S pads (what I rock), or Hawk street compound, and you will feel a massive difference. Just a recommendation....
I used 2008 Forester calipers w/brackets, rotors, and of course pads. But the calipers are the same as any other 2 pot caliper, but the rotors are much bigger, so you need he bracket that goes with them. It was a huge upgrade on the front of my OBS, but I did go from 1 pot to these. But I had a set of RS stuff and these were still quite a bit biggerhow much bigger..... are you just using forester rotors and calipers for the upgrade? i ask cuz i have an rs and i like upgrades to!!! does it effect brake bias by going larger on one end and not the other?
