curious: who's going to fit them - yourself? if not, then perhaps buy from the place that's going to fit them, and you'll probably get a good package deal price.
photo of your car? do you think it's truly dumped 40mm? if it's not quite that, then there should be no probs with KONI dampers like Sport or FSD, as an option.
personally, i'd start just with new dampers, and KONI Sport at that (cos i like the option to adjust the rebound). if it still sits lower than you want, change the springs, but i suspect you won't need to.
