Just made my custom STI suspension for my 08. I put 09 front Shocks with 08 STI springs and rear STI struts with STI pink springs. I think it's a good set up for 09 WRXs it will lower car by 10mm and little stiffer rear. I think my spring rates are equal upfront and back (~220). The car handels very well better than before (08 struts/shocks with Cobb springs). Here are the pictures of after install, I don't have stock suspension picture. I think I am the first one who tried this set up.
