Do you have stock front shocks or do you have tokico struts all the way around? What exactly do you not like about your current set up? Ride feel? Cornering ability? Is the car too "boaty" or have too much body roll for your tastes? We need a bit more info from you to correctly suggest a change in the right direction for yourself as a coilover network may be too much for what you want as far as handling and ride experience.
