I have them on my '98 EX with progress group springs. I'm happy with them. I just set them to setting 3 and never adjusted them yet. Ride is very good, and most of the people who drive it say it's very comfortable compared to their lowered cars. With coilovers, your going to have a rougher ride but I don't think you'll be disappointed. No suprises on installation for me but I didn't have a collar to install (for your coilovers). Just remember to not to let your buddy pop in the adjusting tool in the top before you tighten down the top hat (you just have to remove it, but it's kind of a pain).
