I've got a stock DD 2002 wrx sedan, and i plan to keep it as a DD. i recently purchased a set of the sti pink springs. when i got them, the front springs had the white markings (USDM?) and the rears had the blueish (almost lavender?) markings (JDM?). I was told the fitment of this set is for 04+ models (requiring 04+ tophats which i have, and fit with the top of the rear springs)so my questions are:
do i have usdm front springs and jdm rear springs?
i know that if this is the case, the spring rates vary, how detrimental will this be, if at all?
also, im planning on going with the kyb-gr2 struts, any comments on this supposed set-up?
