Just go to a junkyard and get stock springs to put back in it. The drop spindle will not affect ride quality as it only raises the mounting point of the tire and wheel, essentially. If it is not low enough for your liking with stock springs, you can cut them down very successfully with a cut off wheel until you get the ride height that you want. If you cut too much you will end up right back where you started, obviously. If you bought lowered shocks for the front, you will have to put stock length shocks back in with only the spindle.
