Saw your other thread as well, first what I would though is check ture pressures... Very inexpensive... Might be suprised.. Try +1 or +2 from what pressure is indicated on door.. Might notice big improvement especially if current reading is low.. - I remember how I hated my previous car vw cc 2.0T manual thinking needed stiffer setup did this w tire pressures and became so much better -although traded for focus later-
If this doesnt help much, dampers springs would be next... BUT.. Consider this as well, is car clunking at this point? Theres some of us with this pesky clunk so if youre not might be best to wait for now until a proven tested after mkt solution comes up... If already clunking then might as well change parts anyways..
-side note on conti DWS tires you were asking on other thread, had em on my audi a4 before my cc loved them superior improvement vs factory contis
