I have a 1984 500 SEC that is a Euro version. I bought the car used and do not know very much about it. I do know that someone put lowering springs in the car. As a result, I go through a set of rear tires in about 5000 miles because the rear camber cannot be adjusted. I would like to return the suspension to OEM but the car also has the self leveling hydraulic system so I am not sure what springs to use. Most vendors that sell springs say their products fit the car except thiose withthe self-leveling suspension. I have disabled the self-leveling system since the hydraulic pump continued to fail and dump the hydraulic fluid into the crank case, even after several rebuilds. If you are not familiar with my dilemma can you recommend a source of information on this? Thanks very much.
