you cant have the best of both worlds im afraid.. the best suspension setups are the most uncomfortable.
if you get adjustable coilovers.. even on the softest setting you might find it a little harsh. standard dampers with lowered springs.. cheap and cheerful but dont expect anything other than a nice lowered look.
probably the best comprimise is something like koni dampers with eibach springs.. cheap-ish, decent ride and looks good too. i think awesomegti do these as a set.
