I have been looking for a set of lowering springs that drop the back more than the front. My car is higher in the back than the front so I want it to be flat, but that could just be due to the fact that it's a 94

 

Your old springs are probably sagging in the back. Do your research before lowering. If you don't get new shocks at the same time, don't expect the old ones to last long lowered.

New stock rear springs should bring the car back level if that's all you want. If you do want to lower it, strano springs seem to be the best according to most. There are lots of lowering spring threads on here if you do a search. Even more probably on LS1tech.
