to lower to 2 inches you will need coilovers, period.. no spring out there will offer that kinda drop... only coilovers do, and for that you got plenty of options... simply expensive

if i were you suzuky, try tein's superstreet with edfc, i have asked tein once about using different springs and shocks... cost is not cheap to revalve the shocks itself and getting new springs but it'd be worth it just for edfc!

i believe costs were 100 bucks for pair of springs, and 100 for revalving if you go below or above 100lb/ft of the spring rate that is stock on the superstreet, in my case, i purposed and was about to buy the ss coilovers, have the rears down to 400 lb/ft springs, revalve the front and put on 350 lb/ft springs... but the cost was too much for me, but that'd be my ideal setup, and i'd lower 2 inches!
