im surprised the neuspeed stuff didnt do the trick. but anyways, a couple things to remember. dont get the sleeve over crap. yknow the generic sized springs with adjustable perches that you use with stock dampers. throw all those options in the trash. next, buy some better dampers all around. i like tokico/kyb for the cheap end, or koni for some better ones. you shouldnt ever lower your car on stock dampers. after that, call up ground control or progress technology and see what they say. keep in mind lowering usually has an effect on ride quality, and you cant always find a good comprimise going too low. but progress/GC both have tons of experience racing and modifying hondas, they would have a solution for you.

EDIT: oh and you might tell the progress/GC guys which dampers you have. finding ride quality is basically finding springs/dampers that complement each other on the road style you drive on.
