i don't have ersonal experience with the dropzones, but a lot of people have used them because they're cheap and i've read a lot of complaints about how overly stiff they are. i'm running megan racing 2" drop springs and i love them. they cost about the same as dropzones and, from what i've read, everyone who runs them likes them, a lot of people on dropzones aren't so fond of them. the tokico s/r struts are a pretty perfect complement to the megans, or if you wanna go a bit more expensive the s/r's with eibach 1.8" drop springs is one of the favotire setups around here, as that's what was used from the factory on the zx2 s/r
