Errrr, on the ED30 I had the Pro Street S coilovers and they were great........for about 11 months, then the dampers went.....twice!!
I ended up buying Bilstein PS10's and on the softest setting were more comfortable than the Eibachs and the car handled better too.
IMHO, don't get the Eibachs, get Bilsteins - either B14's or B16's. the B14's are a little harder than Eibachs, but still a much better system.
