zeal, ledda, tanabe, those aren't comfortable, those are pretty much lower grade racing suspension that is some what streetable.

i know someone with tanabe ss on his s2000, the ride is very stiff, performence is there, but even on soft setting, the ride is very harsh.

tein ss or apexi ws are the best choice if it's a daily driver.

both tein and apexi is 3 inch height adjustable, tein is 16 way damp adjust, while apexi is auto damp adjust with 20-30% more stiffer springs compared to stock.

they cost about the same also (tein being about 50-100 more).
