i havnt done this yet, myself but have been doing research into it. if u want a wider track then get a set of alum sedan control arms, sedan front sway bar, and sedan cv shafts and you'll be golden. I'm looking at getting the 04-06 sti arms along with said sedan sway bar and cv shafts with some bc racing coilovers. Trying to figure if i wanna go either sedan or wagon whiteline lateral links since they have adjustable track widths. I gotta do some measuring and ill let u guys know what i find out.
