I'm on D2 coilovers. The softest setting isnt soft, it'll still be fairly bumpy and the hardest setting is well hard! You will feel every single raise, dip, patchwork on the road so it will be one thing you have to get used to. If you hit a pot hole, it can be bone jarring. But saying that I'm used to it and driving anything else now feels like a big boat. The only real advantage to coilovers is adjustable ride height so if you dont need that then you could very much spend that money on a nice set of shocks + springs combo.
