Please advise on what years of shocks/springs will fit a 94? Are the later years any stiffer or different? Do springs really sag after 91K miles? Would the shocks be overly worn also? Are the earlier years any softer or different in significant construction? I'm told by Acura dealer can't adjust alignment to spec because of sagging springs. Is this likely? I want same ride quality as stock - not lower or stiffer. Thanks.
