I used Tanabe springs, which are apparently pretty good without spoiling the ride quality. I can attest to this being the case too.
The 2 I know of are the NF210 (NF - Normal Feels and less of a drop) and the DF210 (Drop feels with more of a drop)

I opted for the NF210 as the spring rate is 5% stiffer than shock, which I'd guess the stock shock can take (time will tell!) and the drop is reasonable without having to get aftermarket camber adjusters etc. I'd still recommend a 4 wheel alignment, had mine done yesterday and it's perfect now.
Do you know of any coilovers that are meant to keep a reasonable ride quality? My driveway won't allow me to lower the car by much so I wanted to use coilovers to fine tune it so I don't beach it coming on/off the drive.
