Although I don't recommend the 92 eclipse springs maybe this solves your problem. its a known issue that v6's gs and sometime I4's vibrate when lowered because of the axles ending at a weird angle:
For some it resolves with new axles for others
with the washer fix for others going to stock spriings.

Resolution has already been said. Washer needs to be 1/8" thick and fit over the axle (like 2 1/16" inside diameter or something I will have to dig that up again)."
