lowering springs of sumthin else??

Im finally gonna lower the g. The option Im lookin at right now is a Groudn Control coilover system, it seems quality and its gives up to a 2.5" drop... for 375 dollars. The other option is an Intrax lowering spring set, but that'll only lower the car by 1.5" (for 240 dollars) and I want the car to sit really really low, so I dont know about it.
Im curious if springs off another other car, ie, a 1g eclipse will fit the car. I know those springs should be cheaper, and there will be more choices. Anyones opinion would be greatly appreciated.

Ground Controls are a great choice. The run $399 retail and REQUIRE shocks. If you're going to be dropping it to it's max, you'll need something comperable to the KYB AGX. If you want something that can turn well as well as look good, go for the more expensive Koni Yellows. The FWD DSM stuff since it's identical. Therefore there are usually not more options.
