I don't know about "good ride" coz there are times that it crashes over bumps etc. Leaving stock shocks with Eibach makes the car wallowy over bumps. Forget doing that coz the stock shocks are very very soft to compress and extend.
Ride with Koni and Eibach... well, it's alright.. can get rocky over a series of bumps coz the Koni won't extend that easily so moderate rises up and down in the road will make you rise up and down fairly quick whereas normal cars will rise up slower, and come down slower giving a better ride (good example is at the last exit on the Gore Hill Freeway going out to Artarmon/Chatswood just before you get on the bridge that curves right over the Freeway).
Also you don't want it lower. There are times that it will hit the bump stops; especially when it's a sharp bump that is only on one side. You soon learn to avoid them anyway. The only one so far that I have a problem with is at Epping Road (at Marsfield near the Avaya Building is) where I can only go on the middle lane at 80 (90 is also fine) but in the others, I need to get to 60 to make it through. Maybe the way around it is to cut the bump stops about 15mm. *shrug* However, for me, the perfect setting is 15mm lowered Eibach....
Comparing to Kings, the Kings are a bit softer and the combo of Koni yellow front, reds back + Kings (Shao's old setting) is much more liveable in everyday driving. It's not as sharp over bumps as my setting. Especially the rears where the yellows make it quite stiff though the springs too make it stiff also.
