There was only 3 factory upgrades for the WRX. Leather, sunroof and satnav.
From memory, the 09's got a bigger turbo (VF52???), bigger swaybars, and other various suspension parts as well as a few aesthetic upgrades - dark wheels, red brakes, nicer grille, etc.
2010 saw bluetooth integration, more suspension upgrades and other minor engine tweaks.
2011 saw the wide body kit and more suspension upgrades to compensate for the wider track, different wheels and wheel sizes
2012 was basically the same as 2011 except a new headunit, new paint colours and I think new headlights....
