just mt 2 cents worth but i dont think the front struts on 08 sti are different from gtb its the same part no (i just had 2 replace one off mine f%%#@&) i think its the rears
that are different from spec b will find out tommorow if fronts are the same. I can tell you that the phat spec teins drop the rear off the 08 sti a lot further than 25 mm.Still drives brilliant and phats tweak and advice worked very well on the front end .
